Add packed-c protocol support for crypto service

To provide a lightweight parameter encoding that is aligned to
conventions used by SCMI, the packed-c parameter serialization has
been added to the crypto service.  This builds on generic
components that allow other packed-c service access protocols
to be added easily.  Service level tests have been extended to
use both protobuf and packed-c clients.
