  1. Calculate the policy hash and set it as the value of the HOST_DATA field
    of SNP Guest VMs.
  2. Calculate the hash again in kata-agent.

Add the hash of the agent policy in the HypervisorConfig. For
confidential containers, the hypervisor might need to attach that
information to the Guest VM - useful for remote attestation, to
establish trust in the policy.
