upper_case_acronyms: move lint from style to pedantic lint group

The lint does point out inconsistency with the Rust naming convention,
but the fact that rustc does not warn about the inconsistency by default
means that clippy probably should not warn by default either.

Fix FP in inherent_to_string when the function has generic parameters

Minimal example of the false positive:
````
struct G;

impl G {
    fn to_string<const _N: usize>(&self) -> String {
        "G.to_string()".to_string()
    }
}

fn main() {
    let g = G;
    g.to_string::<1>();
}
````
Clippy emits an `inherent_to_string` warning, and suggests that we implement `Display` for `G` instead. However, this is not possible, since the generic parameter _N only exists in this function, not in `G` itself. This particular example uses const generics, which is where the issue is most likely to come up, but this PR skips the lint if the `to_string` function has any kind of generic parameters.

changelog: Change unnecessary_wraps to pedantic

There seems to be enough evidence that this lint is not wanted as warn-by-default. Attempted before at #6380. False positives at #6721 and #6427. Actually requested to change the category at #6726.

Teach SpanlessEq binding IDs

changelog: Fix collapsible_match false positive

Fixes #6740

This PR changes the way `SpanlessEq` determines whether two local variables are the same. Instead of checking that the names match, it checks that the `HirId`s match. If local bindings are declared within the expressions that are being compared, `SpanlessEq` will remember bindings that correspond to each other in a `FxHashMap<HirId, HirId>`. This makes `SpanlessEq` more flexible while also fixing false positives.

Example: `{ let x = 1; x + 2 }` is equal to `{ let y = 1; y + 2 }`.

CC `@xFrednet` I think this will resolve some concerns in #6463

changelog: added the new `from_str_radix_10` which sometimes replaces calls to `primitive::from_str_radix` to `str::parse`

This is ready to be merged, although maybe the category should be `pedantic` instead of `style`? I'm not sure where it fits better.

lintcheck: parallelize

By default we use a single thread and one target dir as before.

If `-j n` is passed, use `n` target dirs and run one clippy in each of them.
We need several target dirs because cargo would lock them for a single process otherwise which would prevent the parallelism.
`-j 0` makes rayon use  $thread_count/2 (which I assume is the number of physical cores of a machine) for the number of threads.

Other change:
Show output of clippy being compiled when building it for lintcheck (makes it easier to spot compiler errors etc)
Show some progress indication in the "Linting... foo 1.2.3"  message.
Sort crates before linting (previously crates would be split randomly between target dirs, with the sorting, we try to make sure that even crates land in target dir 0 and odd ones in target dir 1 etc..)

ast: Keep expansion status for out-of-line module items

I.e. whether a module `mod foo;` is already loaded from a file or not.
This is a pre-requisite to correctly treating inner attributes on such modules (https://github.com/rust-lang/rust/issues/81661).

With this change AST structures for `mod` items diverge even more for AST structure for the crate root, which previously used `ast::Mod`.
Therefore this PR removes `ast::Mod` from `ast::Crate` in the first commit, these two things are sufficiently different from each other, at least at syntactic level.
Customization points for visiting a "`mod` item or crate root" were also removed from AST visitors (`fn visit_mod`).
`ast::Mod` itself was refactored away in the second commit in favor of `ItemKind::Mod(Unsafe, ModKind)`.

90d3275b45 lintcheck: parallelize
Use rayon to figure out the threadcount and half that for core count.
For each core, create a target dir that is used.
Otherwise, when running multiple clippys with the same target-dir, cargo would lock the dir and prevent parallelism.
This way we can run multiple clippys at the same time (on root crates) but we sacrifice cache-hits (when we already cargo-checked crate-deps).
