Make use of NoHash hashing for FileId and CrateId
Both of these are mere integers so there is nothing to hash here.
Ideally we would use this for `la_arena::Idx` too, but that doesn't work due to the orphan rule, and `la_arena` is unfortunately a public library so we can't really do much here... Unless we remove the trait restriction but I'd like not to
internal: Re-export standard semantic token types and mods
Should help in preventing future occurences of #13099 by having all token types and mods come through the same place
Add some more highlighting configurations
The following can be enabled/disabled now in terms of highlighting:
- doc comment injection (enabled by default)
- punctuation highlighting (disabled by default)
- operator highlighting (enabled by default)
- punctuation specialized highlighting (disabled by default)
- operator specialized highlighting (disabled by default)
- macro call bang highlighting (disabled by default)
This PR also changes our `attribute` semantic token type to the `decorator` type which landed upstream (but not yet in lsp-types).
Specialized highlighting is disabled by default, as all clients will have to ship something to map these back to the standard punctuation/operator token (we do this in VSCode via the inheritance mapping for example). This is a lot of maintenance work, and not something every client wants to do, pushing that need to use the user. As this is a rather niche use in the first place this will just be disabled by default.
Punctuation highlighting is disabled by default, punctuation is usually something that can be done by the native syntactic highlighting of the client, so there is no loss in quality. The main reason for this though is that punctuation adds a lot of extra token data that we sent over, a lot of clients struggle with applying this, so disabling this improves the UX for a lot of people. Note that we still highlight punctuations with special meaning as that special entity, (the never type `!` will still be tagged as a builtin type if it occurs as such)
Separate highlighting of the macro call bang `!` is disabled by default, as I think people actually didn't like that change that much, though at the same time I feel like not many people even noticed that change (I prefer it be separate, but that's not enough reason for it to be enabled by default I believe :^) )

fix: Fix panics on GATs involving const generics
This workaround avoids constant crashing of rust analyzer when using GATs with const generics,
even when the const generics are only on the `impl` block.
The workaround treats GATs as non-existing if either itself or the parent has const generics and
removes relevant panicking code-paths.
Fixes#11989, fixes#12193
feat: Generate static method using Self::assoc() syntax
This change improves the `generate_function` assist to support generating static methods/associated functions using the `Self::assoc()` syntax. Previously, one could generate a static method, but only when specifying the type name directly (like `Foo::assoc()`). After this change, `Self` is supported as well as the type name.
Fixes#13012
