Move LR speed features to speed 3
Moved several LR related speed features to speed 3. These features
gave good speed/quality trade off.
Borg test results at speed 3(150f):
avg_psnr: ovr_psnr: ssim: speedup:
lowres: 0.255 0.262 0.173 2.8%
midres: 0.076 0.078 0.035 3.3%
ugc360p: 0.117 0.137 0.108 4.7%
(Here are clips that give big quality loss in
lowres: bridge_close_cif.y4m and bridge_far_cif.y4m)
