Lint for bool to integer casts in `cast_lossless`

The lint description says

> Checks for casts between *numerical* types that may be replaced by safe conversion functions.

Which is strictly speaking being violated here, but it seems within the spirit of the lint. I think it is still a useful lint to have, and having a different lint for just this feels excessive. Thoughts?

Fixes #7947

Add Clippy version to Clippy's lint list

Hey, hey, the semester is finally over, and I wanted to get back into hacking on Clippy. It has also been some time since our metadata collection monster has been feed. So, this PR adds a new attribute `clippy::version` to document which version a lint was stabilized. I considered using `git blame` but that would be very hacky and probably not accurate.

I'm also thinking that this attribute can be used to have a `clippy::nightly` lint group which is allow-by-default that delays setting the actual lint group until the defined version is reached. Just something to consider regarding #6623 🙃

This PR only adds the version to 4 lints to keep it reviewable. I'll do a followup PR to add the version to other lints if the implementation is accepted 🙃

6536c586fe Auto merge of #90485 - camsteffen:fmt-args-less-bind, r=m-ou-se
Don't destructure args tuple in format_args!

This allows Clippy to parse the HIR more simply since `arg0` is changed to `_args.0`. (cc rust-lang/rust-clippy#7843). From rustc's perspective, I think this is something between a lateral move and a tiny improvement since there are fewer bindings.

c063203c2b ast: Fix naming conventions in AST structures
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.

e8c4046841 Simplify FullInt Ord impl
`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 🌞
