[libcxx-commits] [libcxx] [libcxx][test] Fix numpunct grouping tests on AIX (PR #91781)

[Xing Xue via libcxx-commits]

https://github.com/xingxue-ibm created https://github.com/llvm/llvm-project/pull/91781

The `grouping` string for locale `en_US.UTF-8` and `fr_FR.UTF-8` on AIX is `3`. This is different from Linux's `3;3` but is the same as Windows. This patch removes `XFAIL: LIBCXX-AIX-FIXME` and change to use the `WIN32` code path.
