fix `single_component_path_imports` FP on `self::<import>::..`
fixes#10549
I noticed that a couple functions in the file I was working on took `cx` as a parameter but didn't use them, so I removed that. Can revert if desired because it isn't related to my changes.
changelog: [`single_component_path_imports`] don't suggest removing import when it is used as `self::<import>::..`

Make redundant_async_block a more complete late pass
This lets us detect more complex situations: `async { x.await }` is simplified into `x` if:
- `x` is an expression without side-effect
- or `x` is an `async` block itself
In both cases, no part of the `async` expression can be part of a macro expansion.
Fixes#10509.
Fixes#10525.

Add `tests_outside_test_module` lint
Adds `tests_outside_test_module` from #10506. This PR **doesn't** close the issue, just resolves task 1.

Mini-fix `double_must_use` for async functions
From Rust 1.67 onwards, the `#[must_use]` attribute also applies to the `Future::Output` (rust-lang/rust#100633). So the lint `double_must_use` was linting all async functions. This PR changes the `double_must_use` lint so it ignores `async` functions.

Partial no-op refactoring of #9948
This contains some prep work for #9948 to keep that change to the minimum, and make it easier to review it.
This should be a noop, but it has some tests from that PR discussion, and should help in the future with the corner case format handling.

Add suggestions to `extra_unused_type_parameters`
Change the `extra_unused_type_parameters` lint to provide machine applicable suggestions rather than just help messages. Exception to this are cases when any unused type parameters appear bounded in where clauses - for now I've deemed these cases unfixable and separated them out. Future work might be able to provide suggestions in these cases.
Also, added a test case for the `avoid_breaking_exported_api` config option.

Added the `[unnecessary_box_returns]` lint

I'm not confident in the name of this lint. Let me know if you can think of something better

In uninit checking, add fallback for polymorphic types
After #10520, we always assumed that polymorphic types do not allow to be left uninitialized. But we can do better, by peeking into polymorphic types and adding a few special cases for going through tuples, arrays (because the length may be polymorphic) and blanket allowing all unions (like MaybeUninit).

Is this the best way to go about this? `unused_parens` will catch the unnecessary ones but emitting them in the first place isn't ideal
