[Core] Generalize ValueObject::MaybeCalculateCompleteType
Summary:
Instead of hardcoding ClangASTContext and ObjCLanguageRuntime, we can
generalize this by creating the method GetRuntimeType in
LanguageRuntime and moving the current MaybeCalculateCompleteType
implementation into ObjCLanguageruntime::GetRuntimeType
