KVM: SVM: Define sev_features and VMPL field in the VMSA
The hypervisor uses the sev_features field (offset 3B0h) in the Save State
Area to control the SEV-SNP guest features such as SNPActive, vTOM,
ReflectVC etc. An SEV-SNP guest can read the sev_features field through
the SEV_STATUS MSR.
While at it, update dump_vmcb() to log the VMPL level.
See APM2 Table 15-34 and B-4 for more details.
