internal: Speed up import searching some more
Pushes the sorting to the caller, meaning additional filtering can be done pre-sorting. Similarly a collect call was pushed to the caller for allowing some other filters to run pre-collecting.
Remove completion limit for trait importing method completions
Fixes https://github.com/rust-lang/rust-analyzer/issues/16075
The < 3 char limit never applied to methods and the amount of completions generated due this is not absolutely massive as not all traits in a project are ever applicable so there is little reason to employ the limit here. Especially as it limits the number of traits we consider, not items (after my changes yesterday), and the number of traits is not the slowing factor here. Tested this in r-a where we have ~800 traits project wide and even when ~260 are applicable there was no noticable slow down from it.
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.

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.

You can see that the items are resolved (excl. trait associated types) since they are semantically highlighted in the doc comment.
fix: try obligation of `IndexMut` when infer
Closes#15842.
This issue arises because `K` is ambiguous if only inferred from `Index` trait, but is unique if inferred from `IndexMut`, but r-a doesn't use this info.
SymbolInformation::kind is finer-grained than the SCIP symbol suffix.
This also fixes a bug where all type aliases where treated like type
parameters.
```
trait SomeTrait {
type AssociatedType; // ← this is SomeTrait#[AssociatedType]
}
type MyTypeAlias = u8; // ← this used to be [MyTypeAlias]
// and now is MyTypeAlias#
```
To build the SymbolInformation::signature_documentation we need access
to the “label” when building the TokenStaticData, preferably without
any markdown markup.
Therefore this refactors ide::hover::render::definition and its helper
functions to give easier access to the label alone.
For local variables, this gets the moniker from the enclosing
definition and stores it into the TokenStaticData.
Then it builds the scip symbol for that moniker when building the
SymbolInformation.
This is meant to implement SymbolInformation::enclosing_symbol, so we
can build the enclosing symbol from the enclosing moniker without
having the full enclosing token's TokenStaticData.
