libstdc++: Remove #error from <semaphore> implementation [PR 100179]
This removes the #error from <bits/semaphore_base.h> for the case where
neither __atomic_semaphore nor __platform_semaphore is defined.
Also rename the _GLIBCXX_REQUIRE_POSIX_SEMAPHORE macro to
_GLIBCXX_USE_POSIX_SEMAPHORE for consistency with the similar
_GLIBCXX_USE_CXX11_ABI macro that can be used to request an alternative
(ABI-changing) implementation.
libstdc++-v3/ChangeLog:
PR libstdc++/100179
* include/bits/semaphore_base.h: Remove #error.
* include/std/semaphore: Do not define anything unless one of
the implementations is available.
