6172: Add qualify path assist r=matklad a=Veykril
This implements a `qualify_path` assist which works quite similar to the `auto_import` assist but instead of adding imports to the file it well, qualifies the path. This PR also moves out the `AutoImportAssets` struct and functions from `auto_import` into a utils submodule as most of this is now shared between `auto_import` and `qualify_path`.
Changes made to `AutoImportAssets` are solely in its `search_for_imports` function which now takes a prefixed parameter to discern between using `find_use_path_prefixed` and `find_use_path` as the former is the required behavior by `auto_import` and the latter by this assist.
For missing imported traits instead of importing this will qualify the path with a trait cast as in:
```rust
test_mod::TestStruct::TEST_CONST<|>
```
becomes
```rust
<test_mod::TestStruct as test_mod::TestTrait>::TEST_CONST
```
and for trait methods ideally it would do the following:
```rust
let test_struct = test_mod::TestStruct {};
test_struct.test_meth<|>od()
```
becomes
```rust
let test_struct = test_mod::TestStruct {};
test_mod::TestTrait::test_method(&test_struct)
```
Fixes#4124.

6299: Diagnose items that are #[cfg]d out r=jonas-schievink a=jonas-schievink
This emits a hint-level diagnostic with `Unnecessary` tag to "gray out" any items whose `#[cfg]` attributes remove the item before name resolution.

Declaration names sounds like a name of declaration -- something you
can use for analysis. It empathically isn't, and is just a label
displayed in various UI. It's important not to confuse the two, least
we accidentally mix semantics with UI (I believe, there's already a
case of this in the FamousDefs at least).
The proper fix I think is:
* move rust-lang/rust library crates to a separate workspace
* when packaging rust-src component, vendor sources of external deps

6276: Extract call_info and completion into separate crates r=matklad a=popzxc
As it was discussed in [zulip](https://rust-lang.zulipchat.com/#narrow/stream/185405-t-compiler.2Fwg-rls-2.2E0/topic/Completion.20refactoring), we need to move `completions` into a separate crate.
Unfortunately, the dependency on `call_info::ActiveParameter` doesn't look easy to get rid of, and it seems to be a topic for a separate PR, thus I also extracted `call_info` into a separate crate (on which both `ide` and `completion` crates depend).
Additionally, a few `FIXME`s in doc-comments were resolved in order to make `tidy` happy.
