AMD's "disable CPUID in usermode" feature is analogous to Intel's "CPUID faulting" feature, but it is advertised and activated differently. The AMD feature is advertised via CPUID.80000021H:EAX.CpuidUserDis[bit 17] and activated by setting HWCR.CpuidUserDis[bit 35].
Add virtualization support for the AMD feature.
