[libc++] Add CMake plumbing for _LIBCPP_HAS_THREAD_API_C11 mode. (#188414)
Introduce CMake option `LIBCXX_HAS_C11_THREAD_API` that explicitly
instructs libc++ to use C11 threads. Make sure
`_LIBCPP_HAS_THREAD_API_C11` is defined properly in the
`<__config_site>` and interacts correctly with platform-based
auto-selection of thread API when it's not explicitly set.
