lavc: rename AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADS 

This cap is currently used to mark multithreading-capable codecs that
wrap external libraries with their own multithreading code. The name is
highly confusing for our API users, since libavcodec ALWAYS handles
thread_count=0 (see commit message in previous commit). Therefore rename
the cap and update its documentation to make its meaning clear.

The old name is kept deprecated until next+1 major bump.

API changes, most recent first:
2021-03-xx - xxxxxxxxxx - lavc 58.132.100 - codec.h
Add AV_CODEC_CAP_OTHER_THREADS as a new name for
AV_CODEC_CAP_AUTO_THREADS. AV_CODEC_CAP_AUTO_THREADS
is now deprecated.
2021-03-12 - xxxxxxxxxx - lavc 58.131.100 - avcodec.h codec.h
Add a get_encode_buffer callback to AVCodecContext, similar to
get_buffer2 but for encoders.
