rustdoc: Cleanup parent module tracking for doc links

Keep ids of the documented items themselves, not their parent modules. Parent modules can be retreived from those ids when necessary.

Fixes https://github.com/rust-lang/rust/issues/108501.
That issue could be fixed in a more local way, but this refactoring is something that I wanted to do since https://github.com/rust-lang/rust/pull/93805 anyway.
