    [VP] 1to3 kernel integration(CL#810055)

    1. integrate kernel for 1to3 case. using avs sampler.
    2. resotre interface descripte sampler offset as 3D sampler.
    3. modify 16align sampler index as 1 to unify with FC and 1to3.

For example:

$ LIBVA_DRIVER_NAME=iHD ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 \
  -v verbose -f rawvideo -pix_fmt nv12 -s:v 1280x720 -i input.yuv \
  -vf 'format=nv12,hwupload,scale_vaapi=w=1920:h=1080,hwdownload,format=nv12' \
  -pix_fmt nv12 -vframes 10 -y test.yuv
