- [x] Removed `?const` and change uses of `?const`
- [x] Added `~const` to the AST. It is gated behind const_trait_impl.
- [x] Validate `~const` in ast_validation.
- [ ] Add enum `BoundConstness` to the HIR. (With variants `NotConst` and
`ConstIfConst` allowing future extensions)
- [ ] Adjust trait selection and pre-existing code to use `BoundConstness`.
- [ ] Optional steps (*for this PR, obviously*)
- [ ] Fix#88155
- [ ] Do something with constness bounds in chalk
rfc3052 followup: Remove authors field from Cargo manifests
Since RFC 3052 soft deprecated the authors field, hiding it from
crates.io, docs.rs, and making Cargo not add it by default, and it is
not generally up to date/useful information for contributors, we may as well
remove it from crates in this repo.

The recursion_limit attribute avoids the following error:
```
error[E0275]: overflow evaluating the requirement `std::ptr::Unique<rustc_ast::Pat>: std::marker::Send`

= help: consider adding a `#![recursion_limit="256"]` attribute to your crate (`rustfmt_nightly`)

rustfmt: load nested out-of-line mods correctly
This should address https://github.com/rust-lang/rustfmt/issues/4874
r? `@Mark-Simulacrum`
Decided to make the change directly in tree here for expediency/to minimize any potential backporting issues, and because there's some subtree sync items I need to get resolved before pulling from r-l/rustfmt
This avoids the following warning:
```
