[llvm] [CAS] Temporarily skip tests on old windows version (PR #170063)

[Steven Wu via llvm-commits]

https://github.com/cachemeifyoucan created https://github.com/llvm/llvm-project/pull/170063

Some windows bots are getting non-deterministic failures when running
CAS unit tests. Try a workaround to disable on older windows version.
