Find warped reference MV
While finding the reference MV for a block, if one neighbouring block's
motion mode is warped motion mode, instead of directly adding that
block's MV to the candidate MV list, we use that neighbouring block's
warped motion parameters to compute a MV for the center point of the
current block, and then add that MV to the candidate MV list.
Borg test result:
avg_psnr ovr_psnr ssim
cam_lowres: -0.507 -0.514 -0.685
lowres: -0.114 -0.122 -0.180
The change is added under ext_warped_motion config flag.
