KVM: SEV: 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. Other commands can then at that point be
used to load/encrypt data into the guest's initial launch image.
For more information see the SEV-SNP specification.
