Change unnecessary_wraps to pedantic

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.

Closes #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

Add the from_str_radix_10 lint

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.

Closes #6713.

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).

r? `@matthiaskrgr`

I found that this will be really helpful if we use a separate repository and want to maintain a all-lints-passing list of crates. See my early experimentation here: https://github.com/flip1995/clippy-lintcheck

```
git submodule update --init
cargo run -- --mode=all
```

Will run the lintcheck tool on all the specified crates in `config/` in that repository.

New lint: default_numeric_fallback

fixes #6064
r? `@flip1995`

As we discussed in [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20.236064/near/224647188) and [here](https://rust-lang.zulipchat.com/#narrow/stream/257328-clippy/topic/Issue.20clippy.236064/near/224746333),   I start implementing this lint from the strictest version.
In this PR, I'll allow the below two cases to pass the lint to reduce FPs.

1. Appearances of unsuffixed numeric literals in `Local` if `Local` has a type annotation, for example:
```rust
// Good.
let x: i32 = 1;

// Also good.
let x: (i32, i32) = if cond {
   (1, 2)
} else {
   (2, 3)
};
```

2. Appearances of unsuffixed numeric literals in args of `Call` or `MethodCall`  if corresponding arguments of their signature have concrete types, for example:
```rust
fn foo_mono(x: i32) -> i32 {
    x
}

fn foo_poly<T>(t: T) -> t {
    t
}

// Good.
let x = foo_mono(13);

// Still bad.
let x: i32 = foo_poly(13);
```

more lintcheck updates

* do some refactoring and renaming here and there
* add comments to functions
* fix bug where git repos would not get checked out to the proper commits (cmd was not actually run in repo directory 😅 )
* print warnings if we can't clone or check out a git repo
* filter out noise from cargo-metadata errors and lint messages that contained absolute file paths (these would change with every pinned-nightly bump, polluting the logs)
