OvmfPkg/AmdSev: Enforce hash verification of kernel blobs
In the AmdSevX64 build, use BlobVerifierLibSevHashes to enforce
verification of hashes of the kernel/initrd/cmdline blobs fetched from
firmware config.
This allows for secure (measured) boot of SEV guests with QEMU's
-kernel/-initrd/-append switches (with the corresponding QEMU support
for injecting the hashes table into initial measured guest memory).
