gccrs: Add missing name resolution to item statements

gccrs: Add missing name resolution to item statements

This fixes the issue but there are two cleanups to do at some point.

  1. misc namesapce this is a scope AST namespace where we dump resolution
     info when its not defined here. This occurs in the case such as nested
     scopes where the nested scope is popped and we hit an assertion.
     Outside of name resolution this requirement shouldnt really apply
     it should be permissive to allow for this

  2. We reuse our existing name resolution pieces here for Traits and impl
     blocks we should start doing this for the other statements.

Fixes #2238
