Refactor trait map and module symbol resolution code to allow usage for parsed declarations

[tritao]

Description

This PR unifies the codepaths in trait map and name resolution code so they can work for both parsed and typed declarations.
It does this by introducing wrapper types for the output of resolving of names.

This is an intermediate step to being able to use this code on the new symbol resolving pass.

While this adds a little bit of minor bloat to the code, I think it's an acceptable further step to be able to do re-use the code in steps before type-checking.
