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.

6751: Use the right `def_crate` for builtin macros r=jonas-schievink a=jonas-schievink
Fixes the incorrect macro resolution in https://github.com/rust-analyzer/rust-analyzer/issues/6716
No test, because diagnostics do not get remapped correctly for some reason. I've checked manually that this fixes the resolution errors.

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.

6597: Upgrade Chalk r=flodiebold a=flodiebold
Also make overflow depth and max type size configurable through env variables. This can be helpful at least for debugging.
Tests currently fail because of rust-lang/chalk#656, so we'll need to wait for the next update to merge this.

6733: Update attributes completion list r=jonas-schievink a=Veykril
Might be nice to have them grouped for readability/maintainability similar to how the [reference](https://doc.rust-lang.org/reference/attributes.html#built-in-attributes-index) does it but that would require the use of a `OnceCell` for sorting the entries back after construction.

6734: Emit additional diagnostics for hints/help/etc r=lnicola a=jonas-schievink
This makes rust-analyzer diagnostics match native rustc diagnostics in the terminal more closely. Unfortunately all of this is a bodge, since we already provide this information to the client in the form of `DiagnosticRelatedInformation`, but at least VS Code chooses such a poor UI for these that they don't help much, as evidenced [here](https://twitter.com/yaahc_/status/1335297260444250112) and in https://github.com/rust-lang/rust/issues/79741.
This PR papers over these client UI problems by taking the `DiagnosticRelatedInformation` and turning each one into its own hint-level diagnostic, which makes it show up in the source code. Quick fixes are attached to all resulting diagnostics, which makes them more discoverable.
### Example: "Consider removing this semicolon"

6724: Fix `diagnostics` subcommand, look at all modules r=jonas-schievink a=jonas-schievink

6723: Use correct, full substs for self type in impl r=flodiebold a=flodiebold
Without arbitrary self types, the self type could never refer to the method type parameters, so this wasn't a problem; but with arbitrary self types, it can.
This fixes the crash from #6668; but it doesn't make method resolution work for these methods.

Diagnostics inside proc macros are currently incorrectly placed at their original offset, but inside the containing file. This fixes that, by allowing the creation of `ExpansionInfo` from non-`macro_rules!` macro invocations.
