Summary:
This diff adds **`skipOperationNotPermittedPackets`** to `DecoderParameters`.

Once that is set to `True`, it allows decoder to skip through those packets, that are causing `EPERM` errors and result into stoppage of consuming a stream.

Summary:
Pull Request resolved: https://github.com/pytorch/vision/pull/6432



According to the documentation the packet has to be freed after `av_read_frame()` call.
```
 If pkt->buf is NULL, then the packet is valid until the next
 av_read_frame() or until avformat_close_input(). Otherwise the packet
 is valid indefinitely. In both cases the packet must be freed with
 av_packet_unref when it is no longer needed.
```
