Description: Importing names and building the lookup table happens when building clang modules. This means we may not have a valid clang AST (context) and the clang module loader may be null. #67865 introduced a use of the clang module loader when doing name lookup which meant we crashed when emitting the bridging header as a pch.
Scope: Any interop emitting a pch, potentially wider scope (any C, ObjC, C++ interop).
Risk: Low. This is a revert.
Testing: Unit testing (CI)
