[libcxx] [test] Add XFAIL LIBCXX-WINDOWS-FIXME in 124 tests that fail in the future CI configuration

This makes no attempt yet to look into the why/what for each of them,
but makes the CI configuration useful for tracking further regressions.
After looking into each case, they can either be fixed, or converted
into UNSUPPORTED: windows or XFAIL: windows, once the cause is known
and explained.

A number of the filesystem cases can be fixed by patches that are
currently in review.
