  -----------
  [C++20] [Modules] Don't diagnose duplicated declarations in different modules which is not in file scope

Close https://github.com/llvm/llvm-project/issues/126373

Although the root problems should be we shouldn't place the friend
declaration to the incorrect module, let's avoid bleeding the edge by
stoping diagnosing declarations not in file scope.
