7900: show function params in completion detail r=matklad a=JoshMcguigan
This resolves#7842 by updating the detail for function completions from `-> T` to `fn(T, U) -> V`. I added an expicit unit test for this, `ide_completion::render::fn_detail_includes_args_and_return_type`, which passes.
Lots of other unit tests fail (~60 of them) due to this change, although I believe the failures are purely cosmetic (they were testing the exact format of this output). I'm happy to go update those tests, but before I do that I'd like to make sure this is in fact the format we want for the detail?
edit - I realized `UPDATE_EXPECT=1 cargo test` automatically updates `expect!` tests. Big 👍 to whoever worked on that! So I'll go ahead and update all these tests soon. But I still would like to confirm `fn(T, U) -> V` is the desired content in the `detail` field.

8020: Power up goto_implementation r=matklad a=Veykril
by allowing it to be invoked on references of names, now showing all (trait)
implementations of the given type in all crates instead of just the defining
crate as well as including support for builtin types
Example screenshot of `impl`s of Box in `log`, `alloc`, `std` and the current crate. Before you had to invoke it on the definition where it would only show the `impls` in `alloc`.

8018: Make Ty wrap TyKind in an Arc r=flodiebold a=flodiebold
... to further move towards Chalk.
This is a bit of a slowdown (218ginstr vs 213ginstr for inference on RA), even though it allows us to unwrap the Substs in `TyKind::Ref` etc..

What happens here is that we lower `: ` to a missing expression, and
then correctly record that the corresponding field expression resolves
to a specific field. Where we fail is in the mapping of syntax to this
missing expression. Doing it via `ast_field.expr()` fails, as that
expression is `None`. Instead, we go in the opposite direcition and ask
each lowered field about its source.
This works, but has wrong complexity `O(N)` and, really, the
implementation is just too complex. We need some better management of
data here.
use vec![] instead of Vec::new() + push()
avoid redundant clones
use chars instead of &str for single char patterns in ends_with() and starts_with()
allocate some Vecs with capacity to avoid unneccessary resizing
7873: Consider unresolved qualifiers during flyimport r=matklad a=SomeoneToIgnore
Closes https://github.com/rust-analyzer/rust-analyzer/issues/7679
Takes unresolved qualifiers into account, providing better completions (or none, if the path is resolved or do not match).
Does not handle cases when both path qualifier and some trait has to be imported: there are many extra issues with those (such as overlapping imports, for instance) that will require large diffs to address.
Also does not do a fuzzy search on qualifier, that requires some adjustments in `import_map` for better queries and changes to the default replace range which also seems relatively big to include here.

7813: Inline TypeCtor into Ty r=flodiebold a=Veykril
This removes the `ApplicationTy` variant from `Ty` bringing the representation a lot closer to chalk's `TyKind`.

7804: Introduce TypeCtor::Scalar r=lnicola a=Veykril
`TypeCtor::Int(..) | TypeCtor::Float(..) | TypeCtor::Char | TypeCtor::Bool` => `TypeCtor::Scalar(..)`, in this case we can actually just straight up use `chalk_ir::Scalar` already since its just a POD without any IDs or anything.

7145: Proper handling $crate Take 2 [DO NOT MERGE] r=edwin0cheng a=edwin0cheng
Similar to previous PR (#7133) , but improved the following things :
1. Instead of storing the whole `ExpansionInfo`, we store a similar but stripped version `HygieneInfo`.
2. Instread of storing the `SyntaxNode` (because every token we are interested are IDENT), we store the `TextRange` only.
3. Because of 2, we now can put it in Salsa.
4. And most important improvement: Instead of computing the whole frames every single time, we compute it recursively through salsa: (Such that in the best scenario, we only need to compute the first layer of frame)
```rust
let def_site = db.hygiene_frame(info.def.file_id);
let call_site = db.hygiene_frame(info.arg.file_id);
HygieneFrame { expansion: Some(info), local_inner, krate, call_site, def_site }
```
The overall speed compared to previous PR is much faster (65s vs 45s) :

This is done by adding a `ret_type` method to `hir::Function`.
I followed `assoc_fn_params` convention by creating a new `RetType` type,
that contains the actual return type accessible via a `ty` method.
