Update to nightly-2022-12-18

This brings us on par with 1.67 due for release on January 26.

The mergify stuff we forgot to fully remove is the only thing passing, actual GHA looks busted.
Will try to trigger GHA by closing and reopening the PR, can't really find any other controls :/.

EDIT: phew, that did actually work.

Guess this brought in a rustfmt update as well (kind of wild it can do this sort of macro reformatting, at all):

$ rustfmt --check tests/ui/**/*.rs
Diff in /home/runner/work/rust-gpu/rust-gpu/tests/ui/image/format.rs at line 5:

 #[spirv(fragment)]
 pub fn main(
-    #[spirv(descriptor_set = 0, binding = 0)] image: &Image!(2D, format=rgba32f, sampled),
+    #[spirv(descriptor_set = 0, binding = 0)] image: &Image!(2D, format = rgba32f, sampled),
     output: &mut glam::Vec4,
 ) {
     let texel = image.fetch(glam::IVec2::new(0, 1));

And apparently a clippy --fix can introduce bad formatting 🙄

[eddyb]

I found several instances of "{}", " - that indicates likely a bad replacement, where instead of formatting, you're printing the format string verbatim.

This is likely due to the editions, maybe we need to revive a partial version of my PR to switch to Rust 2021.

[eddyb]

Looks like clippy got fixed in:

• uninlined_format_args: Ignore assert! and debug_assert! before 2021 edition rust-lang/rust-clippy#10055

which got sync'd into rust-lang/rust in:

• Update Clippy rust-lang/rust#105827

So theoretically updating to nightly-2022-12-18 should get us fixed clippy (that will not suggest incorrect changes on pre-Rust2021 code).

Alternatively, we could #![allow(...)] the lint for now, or try to land some version of #953 - I don't have a strong preference.

[oisyn]

I'll try updating to nightly-2022-12-18. If that gives us headaches we can always just allow.
