KVM: SVM: Add KVM_SEV_SNP_LAUNCH_START command
KVM_SEV_SNP_LAUNCH_START begins the launch process for an SEV-SNP guest.
The command initializes a cryptographic digest context used to construct
the measurement of the guest. If the guest is expected to be migrated,
the command also binds a migration agent (MA) to the guest.
For more information see the SEV-SNP specification.
