Deprecate refine search stage

With the new oct-diamond search pattern, the additional refinement
search that checks up to 24 motion vector points is no longer needed.
The compression performance change in speed 1 and 5 are both minor,
less than 0.03% gains in lowres, midres, and ugc360p.

On a single clip bus_cif at 1000 kbps tested in speed 5, the speed
is slightly up by 1.5%.
