Add configuration for `semicolon_block` lints
Does exactly what it says on the tin, suggests moving a block's final semicolon inside if it's multiline and outside if it's singleline.
I don't really like how this is implemented so I'm not too sure if this is ready yet. Alas, it might be ok.

Switch to `EarlyBinder` for `explicit_item_bounds`
Part of the work to finish https://github.com/rust-lang/rust/issues/105779.
This PR adds `EarlyBinder` to the return type of the `explicit_item_bounds` query and removes `bound_explicit_item_bounds`.

Document that `cargo clippy --fix` implies `--all-targets`
In [`cargo fix`'s documentation](https://doc.rust-lang.org/cargo/commands/cargo-fix.html) they indicate that `fix` implies `--all-targets` if no target is supplied. As Clippy uses Cargo under the hood, this also applies to Clippy, but we didn't document that behaviour.
This PR changes that

Don't apply `string_lit_as_bytes` if in macro expansion
The following code will emit a warning on both w! and h!, despite there being nothing the user (or library author) could do about it:
```rust
#![warn(clippy::string_lit_as_bytes)]
use windows::w;
use windows::h;
fn main() {
let _w = w!("example");
let _h = h!("example");
}
```
This is because windows-rs will create a binding `const INPUT: &[u8] = $s.as_bytes()`, and changing this to b"$s" is, well, suboptimal. I don't know enough about Rust to know if this is something that can be detected though if it can be I'm happy with closing this in favor of implementing that.
I'm not sure whether this is how it should be done though, as this simply tells clippy to not invoke this even if it's applicable (this also affects the other string lints, but didn't cause any tests to fail).

Improve the help message + add a help span
This would close#10410, because it applies the general consensus achieved in that issue (that replacing `let _ = ...` to `_ = ...` doesn't present any benefits).
I also added a little help message span.

check for `..` pattern in `redundant_pattern_matching`
The `redundant_pattern_matching` lint currently checks for `if let Some(_) = ...`, but not for `if let Some(..) = ...`.
This PR makes sure to also check for the `..` pattern in tuple structs.
It also found one such instance in clippy itself so that shows it's worth checking for this pattern as well 😅

Fix false positive in `allow_attributes`
This would emit a warning if used in a proc-macro with the feature `lint_reasons` enabled. This is now fixed.

Ignore `shadow` warns in code from macro expansions
This PR fixes https://github.com/rust-lang/rust-clippy/issues/9757
I am in doubt if just looking for `pat.span.from_expansion()` would be sufficient instead of looking for both `pat.span.desugaring_kind().is_some()` or `pat.span.from_expansion()`. The tests (including the new one) passes if I leave the only `if pat.span.from_expansion()`. Any feedbacks?
Also, this is my first PR here, sorry for anything and thanks for the patience!

New lint: detect `if` expressions with simple boolean assignments to the same target

Run various queries from other queries instead of explicitly in phases
These are just legacy leftovers from when rustc didn't have a query system. While there are more cleanups of this sort that can be done here, I want to land them in smaller steps.
This phased order of query invocations was already a lie, as any query that looks at types (e.g. the wf checks run before) can invoke e.g. const eval which invokes borrowck, which invokes typeck, ...
use `is_inside_const_context` for `in_constant` util fn
Fixes#10452.
This PR improves the `in_constant` util function to detect more cases of const contexts. Previously this function would not detect cases like expressions in array length position or expression in an inline const block `const { .. }`.

Don't suggest `suboptimal_flops` unavailable in nostd

Add `items_after_test_module` lint
Resolves task *3* of #10506, alongside *1* resolved at #10543 in an effort to help standarize a little bit more testing modules.
