  [C++20] [Modules] [Serialization] Don't record '#pragma once' information in named modules

Close https://github.com/llvm/llvm-project/issues/77995

The cause of the issue is that straight forward that we recorded the
'#pragma once' information in named modules, which is an overlook.

I tried to not record the header's information completely within named
modules. But the tests look not happy with some diagnosing problems,
which needs to be looked in details.
