Add an SEI message to an access unit.

Will add to an existing SEI NAL unit, or create a new one for the message if there is no suitable existing one.

If set, payload_ref must be a RefStruct reference backing payload_data. This function creates a new reference to payload_ref in this case. If payload_ref is NULL, the new message will not be reference counted.
