KVM: x86: hyper-v: Cache HYPERV_CPUID_NESTED_FEATURES CPUID leaf



KVM has to check guest visible HYPERV_CPUID_NESTED_FEATURES.EBX CPUID
leaf to know which Enlightened VMCS definition to use (original or 2022
update). Cache the leaf along with other Hyper-V CPUID feature leaves
to make the check quick.
