Add X509 BCC type to protobuf and update oemcrypto adapter

BCC supports two types of format: CBOR and X509. The latter will be
used by Chrome OS. In case of Prov4, BCC type will be queried by
OEMCrypto_GetBCCType() and the returned value is populated in the
provisioning request.

This CL adds X509 type to protobuf, a call from CDM to query BCC type
and OEMCrypto adapter changes for this call.
