Chuanqi Xu 70195e0d67 [C++20] [Modules] Remove previous workaround for odr hashing enums
Previosly we land
085eae6b86
to workaround the false positive ODR violations in
https://github.com/llvm/llvm-project/issues/76638.

However, we decided to not perform ODR checks for decls from GMF in
https://github.com/llvm/llvm-project/issues/79240 and we land the
corresponding change. So we should be able to remove the workaround now.

The original tests get remained.
