Deprecate QueryState::for_each_unchecked (#10815)
# Objective

Resolves Issue #10772.

## Solution

Added the deprecated warning for QueryState::for_each_unchecked, as
noted in the comments of PR #6773.
Followed the wording in the deprecation messages for `for_each` and
`for_each_mut`

Override QueryIter::fold to port Query::for_each perf gains to select Iterator combinators (#6773)
# Objective
After #6547, `Query::for_each` has been capable of automatic
vectorization on certain queries, which is seeing a notable (>50% CPU
time improvements) for iteration. However, `Query::for_each` isn't
idiomatic Rust, and lacks the flexibility of iterator combinators.

Ideally, `Query::iter` and friends should be able to achieve the same
results. However, this does seem to blocked upstream
(rust-lang/rust#104914) by Rust's loop optimizations.

## Solution
This is an intermediate solution and refactor. This moves the
`Query::for_each` implementation onto the `Iterator::fold`
implementation for `QueryIter` instead. This should result in the same
automatic vectorization optimization on all `Iterator` functions that
internally use fold, including `Iterator::for_each`, `Iterator::count`,
etc.

With this, it should close the gap between the two completely.
Internally, this PR changes `Query::for_each` to use
`query.iter().for_each(..)` instead of the duplicated implementation.

Separately, the duplicate implementations of internal iteration (i.e.
`Query::par_for_each`) now use portions of the current `Query::for_each`
implementation factored out into their own functions.

This also massively cleans up our internal fragmentation of internal
iteration options, deduplicating the iteration code used in `for_each`
and `par_iter().for_each()`.

---

## Changelog
Changed: `Query::for_each`, `Query::for_each_mut`, `Query::for_each`,
and `Query::for_each_mut` have been moved to `QueryIter`'s
`Iterator::for_each` implementation, and still retains their performance
improvements over normal iteration. These APIs are deprecated in 0.13
and will be removed in 0.14.

Mention DynamicSceneBuilder in scene example (#10441)
# Objective

Make ```DynamicSceneBuilder``` more visible to new bevy learners!
```DynamicSceneBuilder``` is likely to be the most appropriate tool to use when creating dynamic scenes in all but the simplest scenarios. However, it's not mentioned in the scene example. This PR aims to fix this.

## Solution

I've modified the comment above where the ```DynamicScene``` is created to note that ```DynamicSceneBuilder``` can also be used to create the scene. I believe this is the best approach to introduce ```DynamicSceneBuilder``` without adding additional complexity to the example.

Add GltfLoaderSettings (#10804)
# Objective

when loading gltfs we may want to filter the results. in particular, i
need to be able to exclude cameras.

i can do this already by modifying the gltf after load and before
spawning, but it seems like a useful general option.

## Solution

add `GltfLoaderSettings` struct with bool members:
- `load_cameras` : checked before processing camera nodes.
- `load_lights` : checked before processing light nodes
- `load_meshes` : checked before loading meshes, materials and morph
weights

Existing code will work as before. Now you also have the option to
restrict what parts of the gltf are loaded. For example, to load a gltf
but exclude the cameras, replace a call to
`asset_server.load("my.gltf")` with:
```rust
asset_server.load_with_settings(
    "my.gltf",
    |s: &mut GltfLoaderSettings| {
        s.load_cameras = false;
    }
);
```

Allow removing and reloading assets with live handles (#10785)
# Objective

Fixes #10444 

Currently manually removing an asset prevents it from being reloaded
while there are still active handles. Doing so will result in a panic,
because the storage entry has been marked as "empty / None" but the ID
is still assumed to be active by the asset server.

Patterns like `images.remove() -> asset_server.reload()` and
`images.remove() -> images.insert()` would fail if the handle was still
alive.

## Solution

Most of the groundwork for this was already laid in Bevy Asset V2. This
is largely just a matter of splitting out `remove` into two separate
operations:

* `remove_dropped`: remove the stored asset, invalidate the internal
Assets entry (preventing future insertions with the old id), and recycle
the id
* `remove_still_alive`: remove the stored asset, but leave the entry
otherwise untouched (and dont recycle the id).

`remove_still_alive` and `insert` can be called any number of times (in
any order) for an id until `remove_dropped` has been called, which will
invalidate the id.

From a user-facing perspective, there are no API changes and this is non
breaking. The public `Assets::remove` will internally call
`remove_still_alive`. `remove_dropped` can only be called by the
internal "handle management" system.

---

## Changelog

- Fix a bug preventing `Assets::remove` from blocking future inserts for
a specific `AssetIndex`.

Fix prepass binding issues causing crashes when not all prepass bindings are used (#10788)
# Objective

Fixes https://github.com/bevyengine/bevy/issues/10786

## Solution

The bind_group_layout entries for the prepass were wrong when not all 4
prepass textures were used, as it just zipped [17, 18, 19, 20] with the
smallvec of prepass `bind_group_layout` entries that potentially didn't
contain 4 entries. (eg. if you had a depth and motion vector prepass but
no normal prepass, then depth would be correct but the entry for the
motion vector prepass would be 18 (normal prepass' spot) instead of 19).

Change the prepass `get_bind_group_layout_entries` function to return an
array of `[Option<BindGroupLayoutEntryBuilder>; 4]` and only add the
layout entry if it exists.

try_insert Aabbs (#10801)
# Objective

avoid panics from `calculate_bounds` systems if entities are despawned
in PostUpdate.

there's a running general discussion (#10166) about command panicking.
in the meantime we may as well fix up some cases where it's clear a
failure to insert is safe.

## Solution

Fix nested generics in Reflect derive (#10791)
# Objective

> Issue raised on
[Discord](https://discord.com/channels/691052431525675048/1002362493634629796/1179182488787103776)

Currently the following code fails due to a missing `TypePath` bound:

```rust
#[derive(Reflect)] struct Foo<T>(T);
#[derive(Reflect)] struct Bar<T>(Foo<T>);
#[derive(Reflect)] struct Baz<T>(Bar<Foo<T>>);
```

## Solution

Add `TypePath` to the per-field bounds instead of _just_ the generic
type parameter bounds.

### Related Work

It should be noted that #9046 would help make these kinds of issues
easier to work around and/or avoid entirely.

Print precise and correct watch warnings (and only when necessary) (#10787)
# Objective

Fixes #10401 

## Solution

* Allow sources to register specific processed/unprocessed watch
warnings.
* Specify per-platform watch warnings. This removes the need to cover
all platform cases in one warning message.
* Only register watch warnings for the _processed_ embedded source, as
warning about watching unprocessed embedded isn't helpful.

## Changelog

- Asset sources can now register specific watch warnings.

Swap material and mesh bind groups (#10485)
# Objective
- Materials should be a more frequent rebind then meshes (due to being
able to use a single vertex buffer, such as in #10164) and therefore
should be in a higher bind group.

---

## Changelog
- For 2d and 3d mesh/material setups (but not UI materials, or other
rendering setups such as gizmos, sprites, or text), mesh data is now in
bind group 1, and material data is now in bind group 2, which is swapped
from how they were before.

## Migration Guide
- Custom 2d and 3d mesh/material shaders should now use bind group 2
`@group(2) @binding(x)` for their bound resources, instead of bind group
1.
- Many internal pieces of rendering code have changed so that mesh data
is now in bind group 1, and material data is now in bind group 2.
Semi-custom rendering setups (that don't use the Material or Material2d
APIs) should adapt to these changes.

Save an instruction in EntityHasher (#10648)
# Objective

Keep essentially the same structure of `EntityHasher` from #9903, but
rephrase the multiplication slightly to save an instruction.

## Solution

Today, the hash is
```rust
        self.hash = i | (i.wrapping_mul(FRAC_U64MAX_PI) << 32);
```
with `i` being `(generation << 32) | index`.

Expanding things out, we get
```rust
i | ( (i * CONST) << 32 )
= (generation << 32) | index | ((((generation << 32) | index) * CONST) << 32)
= (generation << 32) | index | ((index * CONST) << 32)  // because the generation overflowed
= (index * CONST | generation) << 32 | index
```

What if we do the same thing, but with `+` instead of `|`? That's almost
the same thing, except that it has carries, which are actually often
better in a hash function anyway, since it doesn't saturate. (`|` can be
dangerous, since once something becomes `-1` it'll stay that, and
there's no mixing available.)

```rust
(index * CONST + generation) << 32 + index
= (CONST << 32 + 1) * index + generation << 32
= (CONST << 32 + 1) * index + (WHATEVER << 32 + generation) << 32 // because the extra overflows and thus can be anything
= (CONST << 32 + 1) * index + ((CONST * generation) << 32 + generation) << 32 // pick "whatever" to be something convenient
= (CONST << 32 + 1) * index + ((CONST << 32 + 1) * generation) << 32
= (CONST << 32 + 1) * index +((CONST << 32 + 1) * (generation << 32)
= (CONST << 32 + 1) * (index + generation << 32)
= (CONST << 32 + 1) * (generation << 32 | index)
= (CONST << 32 + 1) * i
```

So we can do essentially the same thing using a single multiplication
instead of doing multiply-shift-or.

LLVM was already smart enough to merge the shifting into a
multiplication, but this saves the extra `or`:

<https://rust.godbolt.org/z/MEvbz4eo4>

It's a very small change, and often will disappear in load latency
anyway, but it's a couple percent faster in lookups:

![image](https://github.com/bevyengine/bevy/assets/18526288/c365ec85-6adc-4f6d-8fa6-a65146f55a75)

(There was more of an improvement here before #10558, but with `to_bits`
being a single `qword` load now, keeping things mostly as it is turned
out to be better than the bigger changes I'd tried in #10605.)

Provide GlobalsUniform in UiMaterial shaders (#10739)
# Objective

`GlobalsUniform` provides the current time to shaders, which is useful
for animations. `UiMaterial` is an abstraction that makes it easier to
write custom shaders for UI elements.
This PR makes it possible to use the `GlobalsUniform` in `UiMaterial`
shaders.

## Solution

The `GlobalsUniform` is bound to `@group(0) @binding(1)`. It is
accessible in shaders with:
```wgsl
#import bevy_render::globals::Globals

@group(0) @binding(1)
var<uniform> globals: Globals;
```

Added `GlobalsUniform` in `UiMaterial` shaders

Add clippy::manual_let_else at warn level to lints (#10684)
# Objective

Related to #10612.

Enable the
[`clippy::manual_let_else`](https://rust-lang.github.io/rust-clippy/master/#manual_let_else)
lint as a warning. The `let else` form seems more idiomatic to me than a
`match`/`if else` that either match a pattern or diverge, and from the
clippy doc, the lint doesn't seem to have any possible false positive.

Bind group layout entries (#10224)
# Objective

- Follow up to #9694

## Solution

- Same api as #9694 but adapted for `BindGroupLayoutEntry`
- Use the same `ShaderStages` visibilty for all entries by default
- Add `BindingType` helper function that mirror the wgsl equivalent and
that make writing layouts much simpler.

Before:
```rust
let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor {
    label: Some("post_process_bind_group_layout"),
    entries: &[
        BindGroupLayoutEntry {
            binding: 0,
            visibility: ShaderStages::FRAGMENT,
            ty: BindingType::Texture {
                sample_type: TextureSampleType::Float { filterable: true },
                view_dimension: TextureViewDimension::D2,
                multisampled: false,
            },
            count: None,
        },
        BindGroupLayoutEntry {
            binding: 1,
            visibility: ShaderStages::FRAGMENT,
            ty: BindingType::Sampler(SamplerBindingType::Filtering),
            count: None,
        },
        BindGroupLayoutEntry {
            binding: 2,
            visibility: ShaderStages::FRAGMENT,
            ty: BindingType::Buffer {
                ty: bevy::render::render_resource::BufferBindingType::Uniform,
                has_dynamic_offset: false,
                min_binding_size: Some(PostProcessSettings::min_size()),
            },
            count: None,
        },
    ],
});
```
After:
```rust
let layout = render_device.create_bind_group_layout(
    "post_process_bind_group_layout"),
    &BindGroupLayoutEntries::sequential(
        ShaderStages::FRAGMENT,
        (
            texture_2d_f32(),
            sampler(SamplerBindingType::Filtering),
            uniform_buffer(false, Some(PostProcessSettings::min_size())),
        ),
    ),
);
```

## Changelog

- Added `BindGroupLayoutEntries` and all `BindingType` helper functions.

## Migration Guide

`RenderDevice::create_bind_group_layout()` doesn't take a
`BindGroupLayoutDescriptor` anymore. You need to provide the parameters
separately

Split WorldQuery into WorldQueryData and WorldQueryFilter (#9918)
# Objective

- Fixes #7680
- This is an updated for https://github.com/bevyengine/bevy/pull/8899
which had the same objective but fell a long way behind the latest
changes


## Solution

The traits `WorldQueryData : WorldQuery` and `WorldQueryFilter :
WorldQuery` have been added and some of the types and functions from
`WorldQuery` has been moved into them.

`ReadOnlyWorldQuery` has been replaced with `ReadOnlyWorldQueryData`. 

`WorldQueryFilter` is safe (as long as `WorldQuery` is implemented
safely).

`WorldQueryData` is unsafe - safely implementing it requires that
`Self::ReadOnly` is a readonly version of `Self` (this used to be a
safety requirement of `WorldQuery`)

The type parameters `Q` and `F` of `Query` must now implement
`WorldQueryData` and `WorldQueryFilter` respectively.

This makes it impossible to accidentally use a filter in the data
position or vice versa which was something that could lead to bugs.
~~Compile failure tests have been added to check this.~~

It was previously sometimes useful to use `Option<With<T>>` in the data
position. Use `Has<T>` instead in these cases.

The `WorldQuery` derive macro has been split into separate derive macros
for `WorldQueryData` and `WorldQueryFilter`.

Previously it was possible to derive both `WorldQuery` for a struct that
had a mixture of data and filter items. This would not work correctly in
some cases but could be a useful pattern in others. *This is no longer
possible.*

---

## Notes

- The changes outside of `bevy_ecs` are all changing type parameters to
the new types, updating the macro use, or replacing `Option<With<T>>`
with `Has<T>`.

- All `WorldQueryData` types always returned `true` for `IS_ARCHETYPAL`
so I moved it to `WorldQueryFilter` and
replaced all calls to it with `true`. That should be the only logic
change outside of the macro generation code.

- `Changed<T>` and `Added<T>` were being generated by a macro that I
have expanded. Happy to revert that if desired.

- The two derive macros share some functions for implementing
`WorldQuery` but the tidiest way I could find to implement them was to
give them a ton of arguments and ask clippy to ignore that.

## Changelog

### Changed
- Split `WorldQuery` into `WorldQueryData` and `WorldQueryFilter` which
now have separate derive macros. It is not possible to derive both for
the same type.
- `Query` now requires that the first type argument implements
`WorldQueryData` and the second implements `WorldQueryFilter`

## Migration Guide

- Update derives

```rust
// old
#[derive(WorldQuery)]
#[world_query(mutable, derive(Debug))]
struct CustomQuery {
    entity: Entity,
    a: &'static mut ComponentA
}

#[derive(WorldQuery)]
struct QueryFilter {
    _c: With<ComponentC>
}

// new 
#[derive(WorldQueryData)]
#[world_query_data(mutable, derive(Debug))]
struct CustomQuery {
    entity: Entity,
    a: &'static mut ComponentA,
}

#[derive(WorldQueryFilter)]
struct QueryFilter {
    _c: With<ComponentC>
}
```
- Replace `Option<With<T>>` with `Has<T>`

```rust
/// old
fn my_system(query: Query<(Entity, Option<With<ComponentA>>)>)
{
  for (entity, has_a_option) in query.iter(){
    let has_a:bool = has_a_option.is_some();
    //todo!()
  }
}

/// new
fn my_system(query: Query<(Entity, Has<ComponentA>)>)
{
  for (entity, has_a) in query.iter(){
    //todo!()
  }
}
```

- Fix queries which had filters in the data position or vice versa.

```rust
// old
fn my_system(query: Query<(Entity, With<ComponentA>)>)
{
  for (entity, _) in query.iter(){
  //todo!()

Ensure instance_index push constant is always used in prepass.wgsl (#10706)
# Objective

 Kind of helps #10509 

## Solution

Add a line to `prepass.wgsl` that ensure the `instance_index` push
constant is always used on WebGL 2. This is not a full fix, as the
_second_ a custom shader is used that doesn't use the push constant, the
breakage will resurface. We have satisfying medium term and long term
solutions. This is just a short term hack for 0.12.1 that will make more
cases work. See #10509 for more details.

fix insert_reflect panic caused by clone_value (#10627)
# Objective

- `insert_reflect` relies on `reflect_type_path`, which doesn't gives
the actual type path for object created by `clone_value`, leading to an
unexpected panic. This is a workaround for it.
- Fix #10590 

## Solution

- Tries to get type path from `get_represented_type_info` if get failed
from `reflect_type_path`.

---

## Defect remaining

- `get_represented_type_info` implies a shortage on performance than
using `TypeRegistry`.

Fix GLTF scene dependencies and make full scene renders predictable (#10745)
# Objective

Fixes #10688

There were a number of issues at play:

1. The GLTF loader was not registering Scene dependencies properly. They
were being registered at the root instead of on the scene assets. This
made `LoadedWithDependencies` fire immediately on load.
2. Recursive labeled assets _inside_ of labeled assets were not being
loaded. This only became relevant for scenes after fixing (1) because we
now add labeled assets to the nested scene `LoadContext` instead of the
root load context. I'm surprised nobody has hit this yet. I'm glad I
caught it before somebody hit it.
3. Accessing "loaded with dependencies" state on the Asset Server is
boilerplatey + error prone (because you need to manually query two
states).

## Solution

1. In GltfLoader, use a nested LoadContext for scenes and load
dependencies through that context.
2. In the `AssetServer`, load labeled assets recursively.
3. Added a simple `asset_server.is_loaded_with_dependencies(id)`

I also added some docs to `LoadContext` to help prevent this problem in
the future.

---

## Changelog

- Added `AssetServer::is_loaded_with_dependencies`
- Fixed GLTF Scene dependencies
- Fixed nested labeled assets not being loaded

Implement Drop for CommandQueue (#10746)
# Objective

- Fixes #10676, preventing a possible memory leak for commands which
owned resources.

## Solution

Implemented `Drop` for `CommandQueue`. This has been done entirely in
the private API of `CommandQueue`, ensuring no breaking changes. Also
added a unit test, `test_command_queue_inner_drop_early`, based on the
reproduction steps as outlined in #10676.

## Notes

I believe this can be applied to `0.12.1` as well, but I am uncertain of
the process to make that kind of change. Please let me know if there's
anything I can do to help with the back-porting of this change.

AssetMetaMode (#10623)
# Objective

Fixes #10157

## Solution

Add `AssetMetaCheck` resource which can configure when/if asset meta
files will be read:

```rust
app
  // Never attempts to look up meta files. The default meta configuration will be used for each asset.
  .insert_resource(AssetMetaCheck::Never)
  .add_plugins(DefaultPlugins)
```


This serves as a band-aid fix for the issue with wasm's
`HttpWasmAssetReader` creating a bunch of requests for non-existent
meta, which can slow down asset loading (by waiting for the 404
response) and creates a bunch of noise in the logs. This also provides a
band-aid fix for the more serious issue of itch.io deployments returning
403 responses, which results in full failure of asset loads.

If users don't want to include meta files for all deployed assets for
web builds, and they aren't using meta files at all, they should set
this to `AssetMetaCheck::Never`.

If users do want to include meta files for specific assets, they can use
`AssetMetaCheck::Paths`, which will only look up meta for those paths.

Currently, this defaults to `AssetMetaCheck::Always`, which makes this
fully non-breaking for the `0.12.1` release. _**However it _is_ worth
discussing making this `AssetMetaCheck::Never` by default**_, given that
I doubt most people are using meta files without the Asset Processor
enabled. This would be a breaking change, but it would make WASM / Itch
deployments work by default, which is a pretty big win imo. The downside
is that people using meta files _without_ processing would need to
manually enable `AssetMetaCheck::Always`, which is also suboptimal.

When in `AssetMetaCheck::Processed`, the meta check resource is ignored,
as processing requires asset meta files to function.

In general, I don't love adding this knob as things should ideally "just
work" in all cases. But this is the reality of the current situation.

- Added `AssetMetaCheck` resource, which can configure when/if asset
meta files will be read

Ran cargo fmt on benches crate (#10758)

## Solution

- Ran `cargo fmt` in the `benches` crate.

## Notes

I accidentally came across this when working on the `Drop`
implementation for `CommandQueue` and rather embarrassingly let it sneak
into my PR there. I think it makes sense to ensure this crate is also
well formatted to avoid it in the future.

Wait until FixedUpdate can see events before dropping them (#10077)
## Objective
 
Currently, events are dropped after two frames. This cadence wasn't
*chosen* for a specific reason, double buffering just lets events
persist for at least two frames. Events only need to be dropped at a
predictable point so that the event queues don't grow forever (i.e.
events should never cause a memory leak).
 
Events (and especially input events) need to be observable by systems in
`FixedUpdate`, but as-is events are dropped before those systems even
get a chance to see them.
 
## Solution
 
Instead of unconditionally dropping events in `First`, require
`FixedUpdate` to first queue the buffer swap (if the `TimePlugin` has
been installed). This way, events are only dropped after a frame that
runs `FixedUpdate`.
 
## Future Work

In the same way we have independent copies of `Time` for tracking time
in `Main` and `FixedUpdate`, we will need independent copies of `Input`
for tracking press/release status correctly in `Main` and `FixedUpdate`.

--
 
Every run of `FixedUpdate` covers a specific timespan. For example, if
the fixed timestep `Δt` is 10ms, the first three `FixedUpdate` runs
cover `[0ms, 10ms)`, `[10ms, 20ms)`, and `[20ms, 30ms)`.
 
`FixedUpdate` can run many times in one frame. For truly
framerate-independent behavior, each `FixedUpdate` should only see the
events that occurred in its covered timespan, but what happens right now
is the first step in the frame reads all pending events.

Fixing that will require timestamped events.

- on ios this is currently the only way to know if an app comes back
from the background which is an important time to to things (like
resetting the badge)

## Solution

- pick up the winit event and forward it to a new `EventWriter`

---

Use as_image_copy where possible (#10733)
# Objective

`wgpu` has a helper method `texture.as_image_copy()` for a common
pattern when making a default-like `ImageCopyTexture` from a texture.

This is used in various places in Bevy for texture copy operations, but
it was not used where `write_texture` is called.

## Solution

- Replace struct `ImageCopyTexture` initialization with
`texture.as_image_copy()` where appropriate

bevy_utils: Export generate_composite_uuid utility function (#10496)
# Objective

The `generate_composite_uuid` utility function hidden in
`bevy_reflect::__macro_exports` could be generally useful to users.

For example, I previously relied on `Hash` to generate a `u64` to create
a deterministic `HandleId`. In v0.12, `HandleId` has been replaced by
`AssetId` which now requires a `Uuid`, which I could generate with this
function.

## Solution

Relocate `generate_composite_uuid` from `bevy_reflect::__macro_exports`
to `bevy_utils::uuid`.

It is still re-exported under `bevy_reflect::__macro_exports` so there
should not be any breaking changes (although, users should generally not
rely on pseudo-private/hidden modules like `__macro_exports`).

I chose to keep it in `bevy_reflect::__macro_exports` so as to not
clutter up our public API and to reduce the number of changes in this
PR. We could have also marked the export as `#[doc(hidden)]`, but
personally I like that we have a dedicated module for this (makes it
clear what is public and what isn't when just looking at the macro
code).

---

## Changelog

- Moved `generate_composite_uuid` to `bevy_utils::uuid` and made it
public
  - Note: it was technically already public, just hidden

Add a depth_bias to Material2d (#10683)
# Objective

It is currently impossible to control the relative ordering of two 2D
materials at the same depth. This is required to implement wireframes
for 2D meshes correctly
(https://github.com/bevyengine/bevy/issues/5881).

## Solution

Add a `Material2d::depth_bias` function that mirrors the existing 3D
`Material::depth_bias` function.

(this is pulled out of https://github.com/bevyengine/bevy/pull/10489)

### Added

- Added `Material2d::depth_bias`

## Migration Guide

`PreparedMaterial2d` has a new `depth_bias` field. A value of 0.0 can be
