x86/cpufeatures: Assign dedicated feature word for CPUID_0x8000001F[EAX]
Collect the scattered SME/SEV related feature flags into a dedicated
word. There are now five recognized features in CPUID.0x8000001F.EAX,
with at least one more on the horizon (SEV-SNP). Using a dedicated word
allows KVM to use its automagic CPUID adjustment logic when reporting
the set of supported features to userspace.
No functional change intended.
