Update browser-ui-test version used in CI
I realized that the extension of `assert-text*` commands was generated not completely valid (it stopped at first "success" and moved instead of running all checks). It was fixed in [this PR](https://github.com/GuillaumeGomez/browser-UI-test/pull/280).
We don't use this feature currently in the rustdoc GUI tests, but just in case...

Fix exposing fields marked unstable or doc hidden
Closes https://github.com/rust-lang/rust/issues/89837
Work towards https://github.com/rust-lang/rust/issues/89554
Filter fields that are marked `doc(hidden)` or are unstable with that feature turned off. This brings structs and enums into alignment behavior-wise when emitting warning/errors about pattern exhaustiveness/reachability.

Return early to fix ICE
This fixes#94627, ICE happens because compiler tries to suggest constraining type parameter but the only constraint is implicit `std::Sized` one, so it gets removed and there is nothing to suggest resulting in ICE.
diagnostics: do not spurriously claim something is "not an iterator"
Fixes a minor regression caused by #94746, where `iter::Filter` is spurriously declared "not an iterator."
rustdoc-json: Include GenericParamDefKind::Type::synthetic in JSON
The rustdoc JSON for
```
pub fn f(_: impl Clone) {}
```
will effectively be
```
pub fn f<impl Clone: Clone>(_: impl Clone) {}
```
where a synthetic generic parameter called `impl Clone` with generic trait bound
`Clone` is added to the function declaration.
The generated HTML filters out these generic parameters by doing
`self.params.iter().filter(|p| !p.is_synthetic_type_param())`, because the
synthetic generic paramter is not of interest to regular users.
For the same reason, we should expose whether or not a generic parameter is
synthetic or not also in the rustdoc JSON, so that rustdoc JSON clients can also
have the option to hide syntehtic generic parameters.

Improve `AdtDef` interning.
This commit makes `AdtDef` use `Interned`. Much of the commit is tedious
changes to introduce getter functions. The interesting changes are in
`compiler/rustc_middle/src/ty/adt.rs`.
