Improve namespace handling in imports. #4153

Closed jonmeow closed 3 months ago

jonmeow commented 3 months ago

This implements a few closely related features:

Starts merging namespaces discovered inside imports.
Stores results of cross-package name lookup as an entry inside the scope.
- Note this is particularly visible with i32.
Moves more of the imported instructions to the import scope.

Note this is primarily for executing the namespace TODO in check.cpp, which is removed here. testdata/namespace/merging_with_indirections.carbon tests key behavior.
