Resolve visibility paths as modules not as types.

Asking for a resolution with `opt_ns = Some(TypeNS)` allows path resolution to look for type-relative paths, leaving unresolved segments behind. However, for visibility paths we really need to look for a module, so we need to pass `opt_ns = None`.

Fixes rust-lang/rust#109146
