4689: Implement return position impl trait / opaque type support r=matklad a=flodiebold
This is working, but I'm not that happy with how the lowering works. We might need an additional representation between `TypeRef` and `Ty` where names are resolved and `impl Trait` bounds are separated out, but things like inference variables don't exist and `impl Trait` is always represented the same way.
Also note that this doesn't implement correct handling of RPIT *inside* the function (which involves turning the `impl Trait`s into variables and creating obligations for them). That intermediate representation might help there as well.

4748: Add an `ImportMap` and use it to resolve item paths in `find_path` r=matklad a=jonas-schievink
Removes the "go faster" queries I added in https://github.com/rust-analyzer/rust-analyzer/pull/4501 and https://github.com/rust-analyzer/rust-analyzer/pull/4506. I've checked this PR on the rustc code base and the assists are still fast.
This should fix https://github.com/rust-analyzer/rust-analyzer/issues/4515.
Note that this does introduce a change in behavior: We now always refer to items defined in external crates using paths through the external crate. Previously we could also use a local path (if for example the extern crate was reexported locally), as seen in the changed test. If that is undesired I can fix that, but the test didn't say why the previous behavior would be preferable.

4721: Hide squiggly for unused and unnecessary diagnostics r=matklad a=GabbeV
Fixes #4229
When working with JavaScript or TypeScript in VSCode unused valiables are faded but don't have a squiggle. This PR makes rust-analyzer work similarly by setting the severity to hint when applying the unnecessary tag.
VSCode usually shows a squiggle for error, warning and information and shows three dots for hint. When the unnecessary tag is present the squiggles will still show up but the three dots will not.
This is my first contribution to open source. Please tell me if i need to do anything more to get this PR considered.
