KVM: SVM: Add KVM_SNP_INIT command
The KVM_SNP_INIT command is used by the hypervisor to initialize the
SEV-SNP platform context. In a typical workflow, this command should be the
first command issued. When creating SEV-SNP guest, the VMM must use this
command instead of the KVM_SEV_INIT or KVM_SEV_ES_INIT.
The flags value must be zero, it will be extended in future SNP support to
communicate the optional features (such as restricted INT injection etc).
