11461: Extract struct from enum variant filters generics r=jo-goro a=jo-goro
Fixes #11452.
This PR updates extract_struct_from_enum_variant. Extracting a struct `A` form an enum like
```rust
enum X<'a, 'b> {
A { a: &'a () },
B { b: &'b () },
}
```
will now be correctly generated as
```rust
struct A<'a> { a: &'a () }
enum X<'a, 'b> {
A(A<'a>),
B { b: &'b () },
}
```
instead of the previous
```rust
struct A<'a, 'b>{ a: &'a () } // <- should not have 'b
This also works for generic type parameters and const generics.
Bounds are also copied, however I have not yet implemented a filter for unneeded bounds. Extracting `B` from the following enum
```rust
enum X<'a, 'b: 'a> {
A { a: &'a () },
B { b: &'b () },
}
```
will be generated as
```rust
struct B<'b: 'a> { b: &'b () } // <- should be `struct B<'b> { b: &'b () }`

11513: internal: Expand the derive attribute into a pseudo expansion r=Veykril a=Veykril
Quoting my comment:
> We generate a very specific expansion here, as we do not actually expand the `#[derive]` attribute
> itself in name res, but we do want to expand it to something for the IDE layer, so that the input
> derive attributes can be downmapped, and resolved as proper paths.
> This is basically a hack, that simplifies the hacks we need in a lot of ide layer places to
> somewhat inconsistently resolve derive attributes.
>
> As such, we expand `#[derive(Foo, bar::Bar)]` into
> ```
> #[Foo]
> #[bar::Bar]
> ();
> ```
> which allows fallback path resolution in hir::Semantics to properly identify our derives.
> Since we do not expand the attribute in nameres though, we keep the original item.
>
> The ideal expansion here would be for the `#[derive]` to re-emit the annotated item and somehow
> use the input paths in its output as well.
> But that would bring two problems with it, for one every derive would duplicate the item token tree
> wasting a lot of memory, and it would also require some way to use a path in a way that makes it
> always resolve as a derive without nameres recollecting them.
> So this hacky approach is a lot more friendly for us, though it does require a bit of support in

11490: Correctly fix formatting doc tests with generics r=Veykril a=KarlWithK
Before the doc_test would be outputted like this:
```zsh
"Foo<T, U>::t"
```
However, this would cause problems with shell redirection. I've changed it
so when generics are involved we simply wrap the expression under quotes as so:
```zsh
"\"Foo<T, U>::t\""
```
Note:
At the cost of adding this, I had to allocate a new string via
`format!{}`. However, I argue this is alright as this for just for
outputting the name of the doc test.
The following tests have been changed:
```
runnables::tests::doc_test_type_params
runnables::tests::test_doc_runnables_impl_mod
runnables::tests::test_runnables_doc_test_in_impl
```

11481: Display parameter names when hovering over a function pointer r=Veykril a=Vannevelj
Implements #11474
The idea is pretty straightforward: previously we constructed the hover based on just the parameter types, now we pass in the parameter names as well. I went for a quick-hit approach here but I expect someone will be able to point me to a better way of resolving the identifier.
I haven't figured out yet how to actually run my rust-analyzer locally so I can see it in action but the unit test indicates it should work.

Adds the return type of keywords to tool-tips where it makes sense. This applies to: `if`, `else`, `match`, `loop`, `unsafe` and `await`. Thanks to `@Veykril` for sharing the idea of putting return type highlighting on other keywords!

Extract struct from enum variant filters generics
Extracting a struct from an enum variant now filters out only the
generic parameters necessary for the new struct.
Bounds will be copied to the new struct, but unneeded ones are not
filtered out.
Extracting bounds in a where clause are still not implemented.
