6750: Remove documentation query, move doc handling to attributes r=matklad a=Veykril
Fixes#3182
Removes the documentation query in favor of `Attrs::docs`. Attrs already handlded doc comments partially but the alloc saving check was wrong so it only worked when other attributes existed as well. Unfortunately the `new` constructor has to do an intermediate allocation now because we need to keep the order of mixed doc attributes and doc comments.
I've also partially adjusted the `hover` module to have its tests check the changes, it still has some `HasSource` trait usage due to the `ShortLabel` trait usage, as that is only implemented on the Ast parts and not the Hir, should this ideally be implemented for the Hir types as well?(would be a follow up PR of course)

6719: Use items can also have doc comments r=matklad a=Veykril
Prior to this change modules show more docs than they have cause they inherit the docs from documented use items inside of them.

6745: Some more proc macro cleanups r=jonas-schievink a=jonas-schievink
* Remove `ProcMacroClient::dummy` and just use `Option<ProcMacroClient>` instead
* Remember the type of proc macros (later allows us to reject using an incorrect macro type)
* Prepare a few internals for procedural attribute macros

6743: Don't insert blank lines between doc attributes r=Veykril a=Veykril
Fixes#6742.
Doc attributes should be concatenated via a single linebreak as written in the [rustdoc book](https://doc.rust-lang.org/nightly/rustdoc/the-doc-attribute.html).
Also changed the loop to use an iterator to get rid of the `docs.trim_end_matches("\n\n").to_owned()` part using `Itertools::intersperse`.

6731: Add replace_match_with_if_let assist r=matklad a=Veykril
Basically the counterpart to `replace_if_let_with_match`, I personally sometimes want to replace matches like
```rust
match foo {
pat => expr,
_ => (),
}
```
into the corresponding
```rust
if let pat = foo {
expr
}
```
which is the main reasoning behind this.
I put this into the same file as `replace_if_let_with_match` because the are complementing each other and I would probably rename the file to something like `replace_if_let_match` but I didn't do that for now because I was unsure whether git would still view this as a rename or not due to the amount of changes in the file so that the diff is still properly visible for now.
