LOG: [libc++][tests] Update XFAIL annotations for some tests on Windows (#149124)

These tests still fail on Windows with clang-22, as reported in #70225.
This started failing due to the version bump to Clang 22.

Added: 
    

Modified: 
    libcxx/test/libcxx/fuzzing/random.pass.cpp
    libcxx/test/std/depr/depr.c.headers/math_h.pass.cpp
    libcxx/test/std/numerics/c.math/cmath.pass.cpp

Removed:
