[libcxx] [test] Detect the UCRT printf("%a") formatting bug (#99846)
This fixes testing with MinGW, if built without
__USE_MINGW_ANSI_STDIO=1.

On x86 MinGW, such a configuration fails printf tests with long doubles
due to mismatches between 80 and 64 bit long doubles - but on ARM,
there's no such issue, so building without __USE_MINGW_ANSI_STDIO=1 is
perfectly valid there.

Add another similar XFAIL to a libcxxabi test; this test isn't executed
in MSVC environments, so no XFAIL has been needed so far.
