Egor Zhdan 5b7c595b2e [cxx-interop] Remove workarounds for CF_OPTIONS default arguments ...

ClangImporter has logic that infers default arguments of certain C/C++ types, such as the types declared via `CF_OPTIONS`/`NS_OPTIONS` macros.

There were some workarounds in place which triggered for C++ interop mode specifically. The workarounds were applying a heuristic based on the name of the type, which tried to match the behavior to non-C++ interop mode for certain types from the OS SDK. That was not working well for user-defined types, causing source compatibility breakages when enabling C++ interop.

This change replaces the name-based heuristic with a more robust criteria.
