[libcxx] [test] Stop defining LIBCXX-WINDOWS-FIXME

[mstorsjo]

Summary

There are no such markings left - all of them have been fixed or
analyzed.

This closes llvm.org/PR32730 (github issue #32077).

[Mordante]

Nice that this project has been completed!
LGTM! The CI issue seems unrelated to this change, but either rerun the CI or keep an eye out after landing.
