This PR updates the `from_raw_with_void_ptr` lint, which covered
`Box::from_raw`, to also cover the `from_raw` static method of the
`Rc`, `Arc`, `alloc::rc::Weak` and `alloc::sync::Weak` types.
It also improves the description and error messages of this lint.

changelog: [`from_raw_with_void_ptr`]: Now works with the `Rc`, `Arc`, `alloc::rc::Weak` and `alloc::sync::Weak` types.
Improvement for `equatable_if_let`
fixes#9221
This PR makes sure that enums or structs not implementing `PartialEq` trait but still using the `if let` patterns can be linted to be rewritten with `matches!`.
If you added a new lint, here's a checklist for things that will be
checked during review or continuous integration.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[ ] Executed `cargo dev update_lints`
- \[ ] Added lint documentation
- \[x] Run `cargo dev fmt`

changelog: Improve [`equatable_if_let`] with additional `matches!` suggestions.
fix: support `map_or` for `or_fun_call` lint
fixes https://github.com/rust-lang/rust-clippy/issues/8993
The methods defined in `KNOW_TYPES`, except for `map_or`, accepts only one argument, so the matching `if let [arg] = args` works only for these methods.
This PR adds `rest_arg` argument to `check_general_case` method and handling of cases with two arguments to support `map_or`.
changelog: `or_fun_call` support `map_or`
* add `rest_arg` to pass second argument from `map_or(U, F)`
* extract some procedures into closure
* add `rest_arg` to pass second argument from `map_or(U, F)`
* extract some procedures into closure
refac: rename rest_arg/second_arg
refac: organize function argument order
* put `second_arg` next to `arg` argument
Mark `let_underscore_lock` and `let_underscore_drop` as uplifted
Here I've renamed both the uplifted lints, however rustc's `let_underscore_lock` is slightly less capable than the clippy lint as it doesn't catch `parking_lot` types or `Result<Guard, ..>`, should we still remove it? The `Result` change looks like it was unintentional to me so that could probably be fixed upstream
changelog: Uplift [`let_underscore_drop`] to rustc https://github.com/rust-lang/rust/pull/97739
changelog: Remove overlap between rustc's `let_underscore_lock` and Clippy's [`let_underscore_lock`]

fix `box-default` ignoring trait objects' types
This avoids removing the turbofish when the `Box` type is a `dyn` or `impl _`.
This fixes#9621.

Add `unused_format_specs` lint
Currently catches two cases:
An empty precision specifier:
```rust
// the same as {}
println!("{:.}", x);
```
And using formatting specs on `format_args!()`:
```rust
// prints `x.`, not `x .`
println("{:5}.", format_args!("x"));
```
changelog: new lint: [`unused_format_specs`]

Add a suggestion and a note about orphan rules for `from_over_into`
Adds a machine applicable suggestion to convert the `Into` impl into a `From` one to `from_over_into`
Also adds a note explaining that `impl From<Local> for Foreign` is fine if the `Into` type is foreign
Closes#7444
Addresses half of #9638

Fix edition revision ui tests
#9605 had me wondering how the edition revision tests were working for `manual_assert` but not for `@nyurik,` but it turns out `manual_assert`'s tests weren't working either. I checked how `rust-lang/rust` does it and apparently it comes down to whitespace, `//[rev] edition:X` works 😬
Removes the revisions from `match_wild_err_arm` as I couldn't find any edition dependant behaviour there

add tests in `implicit_saturating_sub` lint
This adds more tests to the `implicit_saturating_sub` lint to rule out certain false positives that have appeared in the past.
Now with those false positives out of the equation, we can move the lint to `style`.

changelog: promote [`implicit-saturating-sub`] to the `style` category
