declare_interior_mutable_const, borrow_interior_mutable_const: resolve <T as Trait>::AssocT projections (#14125)
changelog: [`declare_interior_mutable_const`,
`borrow_interior_mutable_const`]: resolve `<T as Trait>::AssocT`
projections

---

This came up during https://github.com/rust-lang/rust/pull/130543 where
we have `<T as AtomicPrimitive>::Assoc = AtomicT` instead of just
`AtomicT` and clippy failed to resolve that properly.

This really needs a review, because

- I don't know if `try_normalize_erasing_regions` is the right thing to
call here.
- I'm not sure if I peel off the correct amount of `ValTree::Branch`
layers (I think I do).

Also, shouldn't this lint's infrastructure rely on `Freeze` trait
(https://github.com/rust-lang/rust/issues/121675) instead of hardcoding
a list of known-to-be-interior-mutable types?

Previously filed this in the main rust repo
(https://github.com/rust-lang/rust/pull/136369), was asked to do it here
instead
(https://github.com/rust-lang/rust/pull/136369#issuecomment-2628527774).
