[NORMATIVE] Scale up mfmv ref step size in 64x64 block

When the coding block size has one side in length of 64 and above,
scale up the mfmv reference search step size from 8 to 16 along
that direction. The midres coding stats get 0.02% better. Among
all the finished hdres points, no negative results showed up.
