Update RLS

Continuation of https://github.com/rust-lang/rust/pull/53610.
Workspaces are tricky - the `json_internal` problem was only reproducible in Rust CI (not sure why it was only relevant to Windows?) and it seems that this was fixed by updating serde_json workspace-wide.

Tested locally in Rust repo and it seems to be working.

Nightlies are currently shipping without RLS, so it'd be great to include this in the next nightlies if possible.

This fixes 'cannot find macro `json_internal!` in this scope' RLS
compilation error in Rust CI, presumably due to a local macro fix in
serde_json 1.0.25
(https://github.com/serde-rs/json/commit/e40cbad70b39a0dd7975be8e5ad9018e2d45f791)

Fix #53525  - Unify E0243, E0244, E0087, E0088, E0089, and E0090 into E0107

Fix #53525

This pr merges all errors related to too many or too few generic arguments in types and functions. E0243, E0244, E0087, E0088, E0089, E0090 errors will no longer be emitted and E0107 will be used instead.

MIR: support user-given type annotations on fns, structs, and enums

This branch adds tooling to track user-given type annotations on functions, structs, and enum variant expressions. The user-given types are passed onto NLL which then enforces them.

cc #47184 — not a complete fix, as there are more cases to cover

Fix compile panic on non existent type return

Reverted the change https://github.com/rust-lang/rust/commit/28a76a90009d605349babcd2755962ab93913327#diff-4ed25c00aceb84666fca639cf8101c7cL1069 which was panicking when returning a type that cannot be found in the current scope and added testing for the compile error.

For example:
```rust
fn addition() -> Wrapper<impl A> {}
```
Where Wrapper is undefined in the scope.

the 3 is because the type arguments are in the 3rd position

Fix #50865: ICE on impl-trait returning functions reaching private items

Adds a test case as suggested in #50865, and implements @petrochenkov's suggestion. Fixes #50865.

Impl-trait-returning functions are marked under a new (low) access level, which they propagate rather than `AccessLevels::Reachable`. `AccessLevels::is_reachable` returns false for such items (leaving stability analysis unaffected), these items may still be visible to the lints phase however.

Stabilize 'attr_literals' feature.
