Switching to the protobuf format helps to make the care_map more extensible. As we have such plans in the future, add the support to parse the protobuf message in the update_verifier. Bug: 77867897 Test: unit tests pass, update_verifier successfully verifies a care_map.pb Change-Id: I9fe83cb4dd3cc8d6fd0260f2a47338fe142d3938
