Update winit dependency to 0.29 (#10702)
# Objective

- Update winit dependency to 0.29

## Changelog

### KeyCode changes

- Removed `ScanCode`, as it was [replaced by
KeyCode](https://github.com/rust-windowing/winit/blob/master/CHANGELOG.md#0292).
- `ReceivedCharacter.char` is now a `SmolStr`, [relevant
doc](https://docs.rs/winit/latest/winit/event/struct.KeyEvent.html#structfield.text).
- Changed most `KeyCode` values, and added more.

KeyCode has changed meaning. With this PR, it refers to physical
position on keyboard rather than the printed letter on keyboard keys.

In practice this means:
- On QWERTY keyboard layouts, nothing changes
- On any other keyboard layout, `KeyCode` no longer reflects the label
on key.
- This is "good". In bevy 0.12, when you used WASD for movement, users
with non-QWERTY keyboards couldn't play your game! This was especially
bad for non-latin keyboards. Now, WASD represents the physical keys. A
French player will press the ZQSD keys, which are near each other,
Kyrgyz players will use "Цфыв".
- This is "bad" as well. You can't know in advance what the label of the
key for input is. Your UI says "press WASD to move", even if in reality,
they should be pressing "ZQSD" or "Цфыв". You also no longer can use
`KeyCode` for text inputs. In any case, it was a pretty bad API for text
input. You should use `ReceivedCharacter` now instead.

### Other changes
- Use `web-time` rather than `instant` crate.
(https://github.com/rust-windowing/winit/pull/2836)
- winit did split `run_return` in `run_onDemand` and `pump_events`, I
did the same change in bevy_winit and used `pump_events`.
- Removed `return_from_run` from `WinitSettings` as `winit::run` now
returns on supported platforms.
- I left the example "return_after_run" as I think it's still useful.
- This winit change is done partly to allow to create a new window after
quitting all windows: https://github.com/emilk/egui/issues/1918 ; this
PR doesn't address.
- added `width` and `height` properties in the `canvas` from wasm
example
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1420567168)

## Known regressions (important follow ups?)
- Provide an API for reacting when a specific key from current layout
was released.
- possible solutions: use winit::Key from winit::KeyEvent ; mapping
between KeyCode and Key ; or .
- We don't receive characters through alt+numpad (e.g. alt + 151 = "ù")
anymore ; reproduced on winit example "ime". maybe related to
https://github.com/rust-windowing/winit/issues/2945
- (windows) Window content doesn't refresh at all when resizing. By
reading https://github.com/rust-windowing/winit/issues/2900 ; I suspect
we should just fire a `window.request_redraw();` from `AboutToWait`, and
handle actual redrawing within `RedrawRequested`. I'm not sure how to
move all that code so I'd appreciate it to be a follow up.
- (windows) unreleased winit fix for using set_control_flow in
AboutToWait https://github.com/rust-windowing/winit/issues/3215 ; ⚠️ I'm
not sure what the implications are, but that feels bad 🤔

## Follow up 

I'd like to avoid bloating this PR, here are a few follow up tasks
worthy of a separate PR, or new issue to track them once this PR is
closed, as they would either complicate reviews, or at risk of being
controversial:
- remove CanvasParentResizePlugin
(https://github.com/bevyengine/bevy/pull/10702#discussion_r1417068856)
- avoid mentionning explicitly winit in docs from bevy_window ?
- NamedKey integration on bevy_input:
https://github.com/rust-windowing/winit/pull/3143 introduced a new
NamedKey variant. I implemented it only on the converters but we'd
benefit making the same changes to bevy_input.
- Add more info in KeyboardInput
https://github.com/bevyengine/bevy/pull/10702#pullrequestreview-1748336313
- https://github.com/bevyengine/bevy/pull/9905 added a workaround on a
bug allegedly fixed by winit 0.29. We should check if it's still
necessary.
- update to raw_window_handle 0.6
  - blocked by wgpu
- Rename `KeyCode` to `PhysicalKeyCode`
https://github.com/bevyengine/bevy/pull/10702#discussion_r1404595015
- remove `instant` dependency, [replaced
by](https://github.com/rust-windowing/winit/pull/2836) `web_time`), we'd
need to update to :
  - fastrand >= 2.0
- [`async-executor`](https://github.com/smol-rs/async-executor) >= 1.7
    - [`futures-lite`](https://github.com/smol-rs/futures-lite) >= 2.0
- Verify license, see
[discussion](https://github.com/bevyengine/bevy/pull/8745#discussion_r1402439800)
  - we might be missing a short notice or description of changes made
- Consider using https://github.com/rust-windowing/cursor-icon directly
rather than vendoring it in bevy.
- investigate [this
unwrap](https://github.com/bevyengine/bevy/pull/8745#discussion_r1387044986)
(`winit_window.canvas().unwrap();`)
- Use more good things about winit's update
- https://github.com/bevyengine/bevy/pull/10689#issuecomment-1823560428

Add consuming builder methods for more ergonomic Mesh creation (#10056)
# Objective

- This PR aims to make creating meshes a little bit more ergonomic,
specifically by removing the need for intermediate mutable variables.

## Solution

- We add methods that consume the `Mesh` and return a mesh with the
specified changes, so that meshes can be entirely constructed via
builder-style calls, without intermediate variables;
- Methods are flagged with `#[must_use]` to ensure proper use;
- Examples are updated to use the new methods where applicable. Some
examples are kept with the mutating methods so that users can still
easily discover them, and also where the new methods wouldn't really be
an improvement.

## Examples

Before:

```rust
let mut mesh = Mesh::new(PrimitiveTopology::TriangleList);
mesh.insert_attribute(Mesh::ATTRIBUTE_POSITION, vs);
mesh.insert_attribute(Mesh::ATTRIBUTE_NORMAL, vns);
mesh.insert_attribute(Mesh::ATTRIBUTE_UV_0, vts);
mesh.set_indices(Some(Indices::U32(tris)));
mesh
```

After:

```rust
Mesh::new(PrimitiveTopology::TriangleList)
    .with_inserted_attribute(Mesh::ATTRIBUTE_POSITION, vs)
    .with_inserted_attribute(Mesh::ATTRIBUTE_NORMAL, vns)
    .with_inserted_attribute(Mesh::ATTRIBUTE_UV_0, vts)
    .with_indices(Some(Indices::U32(tris)))
```

Before:

```rust
let mut cube = Mesh::from(shape::Cube { size: 1.0 });

cube.generate_tangents().unwrap();

PbrBundle {
    mesh: meshes.add(cube),
    ..default()
}
```

After:

```rust
PbrBundle {
    mesh: meshes.add(
        Mesh::from(shape::Cube { size: 1.0 })
            .with_generated_tangents()
            .unwrap(),
    ),
    ..default()
}
```

## Changelog

- Added consuming builder methods for more ergonomic `Mesh` creation:
`with_inserted_attribute()`, `with_removed_attribute()`,
`with_indices()`, `with_duplicated_vertices()`,
`with_computed_flat_normals()`, `with_generated_tangents()`,
`with_morph_targets()`, `with_morph_target_names()`.

fix new clippy lints before they reach stable (#8700)
# Objective

- fix clippy lints early to make sure CI doesn't break when they get
promoted to stable
- have a noise-free `clippy` experience for nightly users

## Solution

- `cargo clippy --fix`
- replace `filter_map(|x| x.ok())` with `map_while(|x| x.ok())` to fix
potential infinite loop in case of IO error

# Objective

- Standardize on screen instructions in examples:
  - top left, bottom left when better
  - white, black when better
  - same margin (12px) and font size (20)

## Solution

- Started with a few examples, let's reach consensus then document and
open issues for the rest

add a default font (#8445)
# Objective

- Have a default font

## Solution

- Add a font based on FiraMono containing only ASCII characters and use
it as the default font
- It is behind a feature `default_font` enabled by default
- I also updated examples to use it, but not UI examples to still show
how to use a custom font

---

## Changelog

* If you display text without using the default handle provided by
`TextStyle`, the text will be displayed

Add parallax mapping to bevy PBR (#5928)
# Objective

Add a [parallax mapping] shader to bevy. Please note that
this is a 3d technique, NOT a 2d sidescroller feature.

## Solution

- Add related fields to `StandardMaterial`
- update the pbr shader
- Add an example taking advantage of parallax mapping

A pre-existing implementation exists at:
https://github.com/nicopap/bevy_mod_paramap/

The implementation is derived from:

https://web.archive.org/web/20150419215321/http://sunandblackcat.com/tipFullView.php?l=eng&topicid=28

Further discussion on literature is found in the `bevy_mod_paramap`
README.

### Limitations

- The mesh silhouette isn't affected by the depth map.
- The depth of the pixel does not reflect its visual position, resulting
  in artifacts for depth-dependent features such as fog or SSAO
- GLTF does not define a height map texture, so somehow the user will
  always need to work around this limitation, though [an extension is in
  the works][gltf]

### Future work

- It's possible to update the depth in the depth buffer to follow the
  parallaxed texture. This would enable interop with depth-based
  visual effects, it also allows `discard`ing pixels of materials when
  computed depth is higher than the one in depth buffer
- Cheap lower quality single-sample method using [offset limiting]
- Add distance fading, to disable parallaxing (relatively expensive)
  on distant objects
- GLTF extension to allow defining height maps. Or a workaround
  implemented through a blender plugin to the GLTF exporter that
  uses the `extras` field to add height map.
- [Quadratic surface vertex attributes][oliveira_3] to enable parallax
  mapping on bending surfaces and allow clean silhouetting.
- noise based sampling, to limit the pancake artifacts.
- Cone mapping ([GPU gems], [Simcity (2013)][simcity]). Requires
  preprocessing, increase depth map size, reduces sample count greatly.
- [Quadtree parallax mapping][qpm] (also requires preprocessing)
- Self-shadowing of parallax-mapped surfaces by modifying the shadow map
- Generate depth map from normal map [link to slides], [blender
question]

## Changelog

- Add a `depth_map` field to the `StandardMaterial`, it is a grayscale
  image where white represents bottom and black the top. If `depth_map`
  is set, bevy's pbr shader will use it to do [parallax mapping] to
  give an increased feel of depth to the material. This is similar to a
  displacement map, but with infinite precision at fairly low cost.
- The fields `parallax_mapping_method`, `parallax_depth_scale` and
  `max_parallax_layer_count` allow finer grained control over the
  behavior of the parallax shader.
- Add the `parallax_mapping` example to show off the effect.
