6666: Support 'go to definition' for self r=jonas-schievink a=Veykril
Also reverts #6660, instead of showing the type it now works like it does for names by returning the declaration we are already on. This for example enables VSCode to show all references(#6665) when executing `go to definition` on the declaration.

6645: Publish diagnostics for macro expansion errors r=matklad a=jonas-schievink
This adds 2 new diagnostics, emitted during name resolution:
* `unresolved-proc-macro`, a weak warning that is emitted when a proc macro is supposed to be expanded, but was not provided by the build system. This usually means that proc macro support is turned off, but may also indicate setup issues when using rust-project.json. Being a weak warning, this should help set expectations when users see it, while not being too obstructive. We do not yet emit this for attribute macros though, just custom derives and `!` macros.
* `macro-error`, which is emitted when any macro (procedural or `macro_rules!`) fails to expand due to some error. This is an error-level diagnostic, but currently still marked as experimental, because there might be spurious errors and this hasn't been tested too well.
This does not yet emit diagnostics when expansion in item bodies fails, just for module-level macros.
Known bug: The "proc macro not found" diagnostic points at the whole item for custom derives, it should just point at the macro's name in the `#[derive]` list, but I haven't found an easy way to do that.

`MacroResult` is redundant
|
|
|
|
| |
This does not parse macros, it expands a macro and parses the *result*

6472: Add `static` modifier for associated functions r=matklad a=p3achyjr
Adds static semantic token modifier to associated functions, resolves #6194
## Info
- Associated functions are more-or-less equivalent to static methods in other languages. This PR checks, for each function, whether that function has a self_param, and whether it's enclosed in a trait/impl.
## Changes
- Added method ```is_associated``` to code_model::Function. This basically gets the source from the ast, and checks whether the enclosing scope is an impl or trait.
- Added `static` to HighlightModifiers
- Added unit test
## Tests
- Ran ```cargo test```

Syntactically, they are indistinguishable from non-raw versions, so it
doesn't make sense to separate then *at the syntax* level.

6365: Do insertion lookahead in algo::diff r=matklad a=Veykril
This is the last blocker for #6287 after this I can update that PR to properly fix things through using `SyntaxRewriter`.
This PR also shuffles tests around a bit and adds some more.
Ideally this is just a hack until we implement a "proper" diff algorithm that approximates a minimal diff. Maybe something like [gumtree](https://github.com/GumTreeDiff/gumtree)?

6393: Remove repetitive inlay hints (take 2) r=matklad a=lnicola
6399: Keep generic annotations when qualifying things r=matklad a=Veykril
The `qualify_path` assists currently eats up already annotated generics in all but one cases which can be annoying if one already pre-fills generics of a type before it's been qualified.
