Import C++ vtables (#7174)
This correctly renders the vtable in SemIR, including allowing overrides in Carbon-derived-from-C++ classes. It doesn't work in lowering because clang walks the methods of the CXXRecordDecl - and we currently don't export anything into the CXXRecordDecl's methods (we do export the fields) - so that's next. This also doesn't teach Clang to affirmatively emit the vtable regardless of the types use in C++ code - or to have Carbon use the vtable in an object's initialization.
