  Log Message:
  -----------
  [libc++] Enable C++ stdatomic.h for all C++ versions (#95498)

This extension is motivated by Android's use of libc++, where
<stdatomic.h> has redirected to <atomic> for many years, long before it
was standardized in C++23.

When libc++'s stdatomic.h is included in C translation units, delegate
to the next stdatomic.h, which could come from Clang or libc.
