8467: Adds impl Deref assist r=jhgg a=jhgg
This PR adds a new `generate_deref` assist that automatically generates a deref impl for a given struct field.

I have a few Q's:
- [x] Should I write more tests, if so, what precisely should I test for?
- [x] I have an inline question on line 65, can someone provide guidance? :)
- [x] I can implement this for `ast::TupleField` too. But should it be a separate assist fn, or should I try and jam both into the `generate_deref`?
- [x] I want to follow this up with an assist on `impl $0Deref for T {` which would automatically generate a `DerefMut` impl that mirrors the Deref as well, however, I could probably use some pointers on how to do that, since I'll have to reach into the ast of `fn deref` to grab the field that it's referencing for the `DerefMut` impl.

8569: Support inherent impls in unnamed consts r=jonas-schievink a=jonas-schievink
It turns out that some proc. macros not only generate *trait* impls wrapped in `const _: () = { ... };`, but inherent impls too. Even though it is questionable whether *custom derives* should produce non-trait impls, this is useful for procedural attribute macros once we support them.

8560: Escape characters in doc comments in macros correctly r=jonas-schievink a=ChayimFriedman2
Previously they were escaped twice, both by `.escape_default()` and the debug view of strings (`{:?}`). This leads to things like newlines or tabs in documentation comments being `\\n`, but we unescape literals only once, ending up with `\n`.
This was hard to spot because CMark unescaped them (at least for `'` and `"`), but it did not do so in code blocks.
This also was the root cause of #7781. This issue was solved by using `.escape_debug()` instead of `.escape_default()`, but the real issue remained.
We can bring the `.escape_default()` back by now, however I didn't do it because it is probably slower than `.escape_debug()` (more work to do), and also in order to change the code the least.
Example (the keyword and primitive docs are `include!()`d at https://doc.rust-lang.org/src/std/lib.rs.html#570-578, and thus originate from macro):

8557: Add an error message to fixture errors r=Veykril a=yoshuawuyts
Improve the error message when folks forget to add an `$0` in one of the fixtures. Figuring this one out was 20 minutes down the drain for me, so figured I might as well make sure nobody else has to go through the same thing in the future. Thanks!

8510: Move cursor position when using item movers r=jonas-schievink a=jonas-schievink
This updates the cursor position when moving items around to stay in the same location within the moved node.
I changed the `moveItem` response to `SnippetTextEdit[]`, since that made more sense to me (the file was ignored by the client anyways, since the edits always apply to the current document). It also matches `onEnter`, which seems logical to me, but please let me know if this doesn't make sense.
There's still a bug in the client-side snippet code that will cause the cursor position to be slightly off when moving parameters in the same line (presumably we don't track the column correctly after deleting `$0`). Not really sure how to fix that immediately, but this PR should already be an improvement despite that bug.

8526: fix: Do not show flyimports in trait or impl declarations r=SomeoneToIgnore a=SomeoneToIgnore
Part of https://github.com/rust-analyzer/rust-analyzer/issues/8518
Removes autoimport suggestions for the case:
> inside trait definitions / impls (trait Trait {$0} / impl Foo {$0}), nothing except the fn, type and const keywords (and the full item completions for trait impls) should appear (currently many types and autoimport suggestions)

8514: Add more profiling spans into type inference r=matklad a=SomeoneToIgnore
Fixes https://github.com/rust-analyzer/rust-analyzer/issues/8503
I've added a minimal set of spans to remove `???` and showcase the underlying issue:

`db.trait_solve` reliably produces the same timings for the same input in the same place for me, despite supposedly being cached by Salsa.
In my perception, this is a bit odd, so I've decided to stop at this point and discuss it with people with better knowledge on the topic.
