Skip instead of failing when prerequisite conditions aren't fulfilled, such as invalid xstate values etc. This patch would make the tests show as skip when run by: make -C tools/testing/selftests/ TARGETS=x86 run_tests

In amx test, Move away from check_cpuid_xsave() and start using arch_prctl() to find out if amx support is present or not. In the kernels where amx isn't present, arch_prctl returns -EINVAL. Hence it is backward compatible.
