Egor Zhdan c8017e7d9f [cxx-interop] Add friend operators to the lookup table properly ...

Previously, `friend` operators declared in C++ classes were added to the lookup table when the class is being imported.

The operators were added to the wrong lookup table if the class is declared in a C++ namespace. Since a namespace can span across multiple Clang modules, its contents should be added to a translation unit level lookup table, not to a module level lookup table.

This change makes sure we add `friend` operators to the lookup table earlier, when we are actually building the lookup table. Note that this is not possible for class template instantiations, because those are instantiated later, so for templates we still handle `friend` operators when importing the instantiation.
