Semantic checks of `impl` restrictions

This PR implements semantic checks for `impl` restrictions proposed in the [Restrictions RFC](https://rust-lang.github.io/rfcs/3323-restrictions.html) (Tracking Issue rust-lang/rust#105077), and linked to a [GSOC idea/proposal](https://github.com/rust-lang/google-summer-of-code/tree/142433eb3b104b2f32bae0b9dfafb78a0a2ac579?tab=readme-ov-file#implementing-impl-and-mut-restrictions).

It lowers the resolved paths of `impl` restrictions from the AST to HIR and into `TraitDef`, and integrates the checks into the coherence phase by extending `check_impl`. As parsing (rust-lang/rust#152943) and path resolution (rust-lang/rust#153556) have already been implemented, this PR provides a working implementation of `impl` restrictions.
