    libstdc++: Use pthread_mutex_clocklock when TSan is active [PR121496]

    This reverts r14-905-g3b7cb33033fbe6 which disabled the use of
    pthread_mutex_clocklock when TSan is active. That's no longer needed,
    because GCC has TSan interceptors for pthread_mutex_clocklock since GCC
    15.1 and Clang has them since 18.1.0 (released March 2024).

    The interceptor was added by
https://github.com/llvm/llvm-project/pull/75713

    libstdc++-v3/ChangeLog:

            PR libstdc++/121496
            * acinclude.m4 (GLIBCXX_CHECK_PTHREAD_MUTEX_CLOCKLOCK): Do not
            use _GLIBCXX_TSAN in _GLIBCXX_USE_PTHREAD_MUTEX_CLOCKLOCK macro.
            * configure: Regenerate.
