avcodec/cbs: allow cbs_read_fragment_content() to skip decomposition of units The caller may not need all units in a fragment in reading only scenarios. They could in fact alter global state stored in the private CodedBitstreamType fields in an undesirable way. With this change, unit decomposition can be skipped based on parsed values within the unit.
