decoder: Ignore RASL NALs after flush
After flush, if the first slice NAL sent to decoder is a CRA
picture, then it may have associated RASL NALs that need to
be skipped as they may contain references to pictures that
are not present in the bitstream that is fed to the decoder.
Currently decoder was handling this case only at the start
of decode and after receiving an EOS NAL. Now it is updated
to ignore such RASL NALs associated with CRA after flush as
well.
This is needed to handle seek in clips, where CRA NALS are
marked as sync points.
