When an async closure captures a variable by move but is constrained to
`AsyncFn` or `AsyncFnMut`, the error message now explains that the
closure kind is the issue and points to the trait bound, similar to the
existing diagnostic for `Fn`/`FnMut` closures.

Tidy: detect ui tests subdirectory changes so `tests/ui/README.md` stays in sync

close: rust-lang#150399

There's an issue where `tests/ui/README.md` isn't updated whenever the ui subdirectory changes.
I've added subdirectory change detection to tidy ~~added a new mention to `triage.toml` to notify `tests/ui/README.md` to also be updated~~.

Improve move error diagnostic for `AsyncFn` closures

When an async closure captures a variable by move but is constrained to `AsyncFn` or `AsyncFnMut`, the error message now explains that the closure kind is the issue and points to the trait bound, similar to the existing diagnostic for `Fn`/`FnMut` closures.

**Before:**
```
error[E0507]: cannot move out of `foos` which is behind a shared reference
  --> src/lib.rs:12:20
   |
11 | async fn foo(foos: &mut [&mut Foo]) -> Result<(), ()> {
   |              ---- move occurs because `foos` has type...
12 |     in_transaction(async || -> Result<(), ()> {
   |                    ^^^^^^^^^^^^^^^^^^^^^^^^^^ `foos` is moved here
13 |         for foo in foos {
   |                    ---- variable moved due to use in coroutine
```

**After:**
```
error[E0507]: cannot move out of `y`, a captured variable in an `AsyncFn` closure
  --> src/lib.rs:9:10
   |
LL |     let y = vec![format!("World")];
   |         - captured outer variable
LL |     call(async || {
   |          ^^^^^^^^ captured by this `AsyncFn` closure
...
help: `AsyncFn` and `AsyncFnMut` closures require captured values to be able
      to be consumed multiple times, but `AsyncFnOnce` closures may consume
      them only once
  --> src/lib.rs:5:27
   |
LL | fn call<F>(_: F) where F: AsyncFn() {}
   |                           ^^^^^^^^^
```

Make `QueryDispatcher::Qcx` an associated type

There's no reason to think that a query dispatcher/vtable would support multiple query-context types, and this simplifies some generic signature boilerplate.

- This is the planned change that was mentioned in rust-lang#151777 (comment).

Implement `cast_slice` for raw pointer types

Tracking issue: rust-lang#149103

This PR implements the method `cast_slice` that defers to the respective `slice_from_raw_parts` call for `*const T`, `*mut T` and `NonNull<T>`, and copies over their documentation.
```rust
impl<T> *const T {
    pub const fn cast_slice(self, len: usize) -> *const [T];
}
impl<T> *mut T {
    pub const fn cast_slice(self, len: usize) -> *mut [T];
}
impl<T> NonNull<T> {
    pub const fn cast_slice(self, len: usize) -> NonNull<[T]>;
}
```

[rustdoc] Add a marker to tell users that there are hidden (deprecated) items in the search results

Someone on mastodon rightfully pointed out that having a visual indication that some search results were hidden would be a good idea if the "hide deprecated items" setting is enabled. In particular if no results are displayed.

It looks like this:

Fix contrast ratio for `Since` element in rustdoc dark theme

Changed `--right-side-color` from `#808080` to `#ababab` in the dark theme.

Verified visually in dark theme, it's now more readable:
