[rkp] Introduce a new request type for attestation request
The attestation keys will be transmitted to the RKP VM along with
the client VM CSR for attestation, using the newly added request
type later.
The retrieval of remotely provisioned keys has been separated in
a subsequent change to unblock the work of handling the new
request.
