changelog: check std::panic::panic_any in panic lint
Rewrite `empty_line_after_doc_comments` and `empty_line_after_outer_attr`, move them from `nursery` to `suspicious`
changelog: [`empty_line_after_doc_comments`], [`empty_line_after_outer_attr`]: rewrite and move them from `nursery` to `suspicious`
They now lint when there's a comment between the last attr/doc comment and the empty line, to cover the case:
```rust
/// Docs for `old_code
// fn old_code() {}
fn new_code() {}
```
When these lints or `suspicious_doc_comments` trigger we no longer trigger any other doc lint as a broad fix for #12917, reverts some of #13002 as the empty line lints cover it
I ended up not doing https://github.com/rust-lang/rust-clippy/issues/12917#issuecomment-2161828859 as I don't think it's needed
Remove `find_format_arg_expr` AST fallback
If the function fails where it shouldn't we can fix that directly, but the fallback path is untested as I'm not aware of a case where it would fail

Shrink `TyKind::FnPtr`.
By splitting the `FnSig` within `TyKind::FnPtr` into `FnSigTys` and `FnHeader`, which can be packed more efficiently. This reduces the size of the hot `TyKind` type from 32 bytes to 24 bytes on 64-bit platforms. This reduces peak memory usage by a few percent on some benchmarks. It also reduces cache misses and page faults similarly, though this doesn't translate to clear cycles or wall-time improvements on CI.

Replace `rustc_semver` with `rustc_session::RustcVersion`
Allows dropping a dependency but there is a behaviour change here, the following versions are no longer accepted:
* `1` (would need to be `1.0` or `1.0.0`)
* `1.0.0-alpha`
* `1.0.0-alpha.2`
* `1.0.0-beta`
But this seems unlikely to effect anybody, I did some GitHub searching and found no occurrences outside our UI tests
