TraitKind -> Trait
TyAliasKind -> TyAlias
ImplKind -> Impl
FnKind -> Fn
All `*Kind`s in AST are supposed to be enums.
Tuple structs are converted to braced structs for the types above, and fields are reordered in syntactic order.
Also, mutable AST visitor now correctly visit spans in defaultness, unsafety, impl polarity and constness.
Reference `clippy_utils` docs on nightly-rustc and some other documentation updates
The `clippy_utils` crate is now part of the nightly-rustc documentation. See [**very beautiful documentation**](https://doc.rust-lang.org/nightly/nightly-rustc/clippy_utils/). This PR references them in our documentation and updates some other documentation.

`cmp_s_u` is a tiny helper function only used by `cmp` and isn't useful on
it's own. Making it a nested function of `cmp` makes that clear and as a
bonus it's easier to call and doesn't require a `#[must_use]` attribute.
Update `str` utils to prevent ICEs and FNs
This PR reworks some string handling for lints regarding enum naming. I hope the refactoring will prevent future ICEs and help with new bug free implementations.
It might be better to review this PR by going through the commits, as `clippy_utils::camel_case` was renamed to `clippy_utils::str_utils` and then changed further. GH sadly doesn't really make the changes that obvious 🙃
Not too much more to say. Have a nice day 🌞

make test module detection more strict
I started with some small improvements to clippy_utils/src/lib.rs, but then found that our "test" module detection would also catch words containing "test" like e.g. "attestation". So I made this a bit more strict (splitting by `'_'` and checking for `test` or `tests`), adding a test case as I went.

Coerce const FnDefs to implement const Fn traits
You can now pass a FnDef to a function expecting `F` where `F: ~const FnTrait`.
