Further tuning of the Gentoo installation instructions.
Based on feedback from the Gentoo repository maintainer, addition of the possibility to install rust-analyzer via rustup.
internal: Move query limits to the caller
Prior we calculated up to `limit` entries from a query, then filtered from that leaving us with less entries than the limit in some cases (which might give odd completion behavior due to items disappearing). This changes it so we filter before checking the limit.
Give a userful error when rustc cannot be found in explicit sysroot
Somehow r-a believed that my sysroot was something weird with no rustc. Probably a me issue, but it was impossible to diagnose since r-a just gave me a plain "No such file or directory". Adding this error makes it clear what happened and allows diagnosing the problem.
internal: Switch to `expected.assert_eq` for `ide` tests
This PR switches from `assert_debug_eq` to `assert_eq` and only compares parts of the result and not the whole. The aim is to only compare parts which are relevant to the test and also make it more readable.
Part of #14268.
## Questions
- [x] Can I use `Vec`? If not, what is the alternative?
I assume I cannot because of: c3a00b5468/docs/dev/architecture.md (L413)
- [x] Should I group it by file, as proposed by Lukas?
```
file_id 1:
source_file_edits:
- Indel { insert: "foo2", delete: 4..7 }
file_id 2:
file_system_edits:
MoveFile AnchoredPathBuf { anchor: FileId(2), path: "foo2.rs", }
```
- [x] Is it okay to ignore `CreateFile` events? They do not have a FileId, which would be problematic, but they do not occur in the existing tests, so I marked them as `unreachable!()` so far.

feat: resolve inherent and implemented associated items in docs
This partially fixes#9694.
Supported:
- Trait methods and constants.
* Due to resolution differences pointed out during the review of the PR, trait associated types are _not_ supported.
- Inherent methods, constants and associated types.
* Inherent associated types are a [nightly feature](https://github.com/rust-lang/rust/issues/8995), and are supported with no additional work in this PR.
Screenshot of VS Code running with the change:

You can see that the items are resolved (excl. trait associated types) since they are semantically highlighted in the doc comment.
