Reduce the motion interpolation filter taps for inter prediction
blocks with widths or heights smaller than or equal to 4 to alleviate the memory
bandwidth increase.

This allows time to investiage the bug related to issue#917, adn the
experiment should be re-enabled after a proper fix is in place for
the issue.

This experiment uses switchable interpolation filter for intra
prediction. Current gain is too small to be useful for AV1.
May explore more for AV2 in the future.

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

This allows it to be enabled/disabled during configure/cmake and also
allows us to specify dependencies.

If 0: superres scaling happens for both width and height.
If 1: superres scaling happens ONLY for width.

In this experiment, sharp image discontinuity in the predicted
block is detected. Based on this discontinuity, we choose
particular LGTs as row and column transforms.

Bitstream syntax, entropy coding, and RD search for LGT are added.
One binary symbol is used to signal whether LGT is used. This
experiment can work independently with the lgt experiment.
