lavfi/lut: Add slice threading support

Used the command for 1080p h264 clip as follow: a). ffmpeg -i input -vf lutyuv="u=128:v=128" -f null /dev/null b). ffmpeg -i input -vf lutrgb="g=0:b=0" -f null /dev/null after enabled the slice threading, the fps change from: a). 144fps to 258fps (lutyuv) b). 94fps to 153fps (lutrgb) in Intel(R) Core(TM) i5-8265U CPU @ 1.60GHz
