x86/cpufeatures: Enable/unmask SEV-SNP CPU feature
With all the required host changes in place, it should now be possible
to initialize SNP-related MSR bits, set up RMP table enforcement, and
initialize SNP support in firmware while maintaining legacy support for
SEV/SEV-ES guests. Go ahead and enable the SNP feature now.
