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!
