[libc++] Replace _LIBCPP_HAS_NO_CONCEPTS with _LIBCPP_STD_VER > 17. NFCI.
All supported compilers that support C++20 now support concepts. So, remove
`_LIB_LIBCPP_HAS_NO_CONCEPTS` in favor of `_LIBCPP_STD_VER > 17`. Similarly in
the tests, remove `// UNSUPPORTED: libcpp-no-concepts`.

Louis Dionne e1ce3dabf0 [libc++] Fix some tests that were broken in the single-threaded configuration
We never noticed it because our CI doesn't actually build against a C
library that doesn't have threading functionality, however building
against a truly thread-free platform surfaces these issues.
