KVM: nSVM: Use KVM-governed feature framework to track "vVM{SAVE,LOAD} enabled"
Track "virtual VMSAVE/VMLOAD exposed to L1" via a governed feature flag
instead of using a dedicated bit/flag in vcpu_svm.
Opportunistically add a comment explaining why KVM disallows virtual
VMLOAD/VMSAVE when the vCPU model is Intel.
No functional change intended.
