Add `CastKind::Transmute` to MIR

~~Nothing actually produces it in this commit, so I don't know how to test it, but it also means it shouldn't be possible for it to break anything.~~

Includes lowering `transmute` calls to it, so it's used.

Significantly optimize `significant_drop_tightening`

The lint is very slow as it doesn't cache the deeply nested check for the attribute. If we cache it, we can reduce the time spent on checking `rustc_borrowck` from 28s to 9s, which is a nice improvement. In the profile, the time inside `has_sig_drop_attr` goes from 66% to 0.2%, which is a lot more reasonable.

6db2d5989f Auto merge of #109119 - lcnr:trait-system-cleanup, r=compiler-errors
a general type system cleanup

removes the helper functions `traits::fully_solve_X` as they add more complexity then they are worth. It's confusing which of these helpers should be used in which context.

changes the way we deal with overflow to always add depth in `evaluate_predicates_recursively`. It may make sense to actually fully transition to not have `recursion_depth` on obligations but that's probably a bit too much for this PR.

also removes some other small - and imo unnecessary - helpers.

Really dogfood clippy

The dogfood success condition was inverted in `tests/dogfood.rs`:

```rust
  assert!(!failed_packages.is_empty(), …);
```

while instead the `failed_packages` collection must be empty:

```rust
  assert!(failed_packages.is_empty(), …);
```

And indeed, several clippy lint source files were not clean and had to be fixed in the process.

Use uninit checking from rustc

rustc has proper heuristics for actually checking whether a type allows being left uninitialized (by asking CTFE). We can now use this for our helper instead of rolling our own bad version with false positives.

Remove box expressions from HIR

After #108516, `#[rustc_box]` is used at HIR->THIR lowering and this is no longer emitted, so it can be removed.

This is based on top of #108471 to help with conflicts, so 43490488ccacd1a822e9c621f5ed6fca99959a0b is the only relevant commit (sorry for all the duplicated pings!)

The documentation retained "vice versa" from the previous incarnation of the lint but the lint itself no longer lints against manual `Hash` implementations with a derived `PartialEq`.

I also adjusted the documentation for `PartialOrd`-`Ord` lint as "vice versa" seemed a little confusing to me there (as to what it was refering to exactly.)
