9814: Generate default impl when converting `#[derive(Debug)]` to manual impl r=yoshuawuyts a=yoshuawuyts
This patch makes it so when you convert `#[derive(Debug)]` to a manual impl, a default body is provided that's equivalent to the original output of `#[derive(Debug)]`. This should make it drastically easier to write custom `Debug` impls, especially when all you want to do is quickly omit a single field which is `!Debug`.
This is implemented for enums, record structs, tuple structs, empty structs - and it sets us up to implement variations on this in the future for other traits (like `PartialEq` and `Hash`).
Thanks!
## Codegen diff
This is the difference in codegen for record structs with this patch:
```diff
struct Foo {
bar: String,
}
impl fmt::Debug for Foo {
fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
- todo!();
+ f.debug_struct("Foo").field("bar", &self.bar).finish()
}
}
```

9808: fix: Look for enum variants and trait assoc functions when looking for lang items r=matklad a=Veykril
Examples for lang enum variants are the `Option` variants.
Assoc trait functions aren't being seen since they aren't declared in the direct module scope.

9806: Add proc_macro crate for the 1.56 ABI r=lnicola a=alexjg
I've copied the latest proc macro source from Rust nightly and modified it to compile on `stable`. This fixes#9795 . Almost everything here is uninteresting copy and paste, the interesting stuff is in `crates/proc_macro_srv/src/abis/mod.rs`. I've left the 1.55 ABI implementation in for now. We did discuss only supporting one nightly ABI so we may want to remove 1.55. That will break code which is pinned to older nightly releases but that seems acceptable to me, what do people think?

9785: feature: Add completion for struct literals in which all fields are visible. r=Veykril a=Afourcat
This PR adds a new completion for struct literal.
It Implements the feature discussed in the issue #9610.
This PR introduce a repetition in the source files `crates/ide_completion/render/pattern.rs` and `crates/ide_completion/render/struct_literal.rs` that may be fix in another PR.
