resolve: Support imports of associated types and glob imports from traits

Follow up to rust-lang#134754, part of rust-lang#134691.
This PR also closes rust-lang#138711 now.

Prohibiting `use Trait::AssocType;` at name resolution stage doesn't make sense, the name itself is perfectly resolveable.
It's a type checker's problem that the necessary generic args are not passed when the imported `AssocType` is used, so an error should be reported there.

And since we can import associated trait items now, glob imports from traits can also be allowed.
