KVM: sefltests: Use CPUID_* instead of X86_FEATURE_* for one-off usage

Rename X86_FEATURE_* macros to CPUID_* in various tests to free up the
X86_FEATURE_* names for KVM-Unit-Tests style CPUID automagic where the
function, leaf, register, and bit for the feature is embedded in its
macro value.

No functional change intended.
