  Log Message:
  -----------
  [C++20] [Modules] Don't add decls from other units to undefinedButUsed set

It is still better to elide the declaration if possible. To overcome the
false positive undefinedButUsed diagnostic, it seems better to not add
declaration from other units to the set actually.
