da0c0c7247 lavfi/hqdn3d: add slice thread optimization 
Enabled one thread per plane, used the test command for 1080P video
(YUV420P format) as follow:

ffmpeg -i 1080p.mp4 -an -vf hqdn3d -f null /dev/nul

This optimization improved the performance about 30% in 1080P YUV420P
case (from 110fps to 143fps), also pass the framemd5 check and FATE.
