KVM: SVM: Add KVM_SEV_SNP_LAUNCH_FINISH command
The KVM_SEV_SNP_LAUNCH_FINISH finalize the cryptographic digest and stores
it as the measurement of the guest at launch.
While finalizing the launch flow, it also issues the LAUNCH_UPDATE command
to encrypt the VMSA pages.
If its an SNP guest, then VMSA was added in the RMP entry as
a guest owned page and also removed from the kernel direct map
so flush it later after it is transitioned back to hypervisor
state and restored in the direct map.
