Speed feature: skip obmc or wm if mv field is identical

Check if the neighbors' motions used by obmc have same parameters
as for the current block. If all the parameters are identical, we
skip trying obmc or warped motion modes.

Two speed features below are added but not turned on by default.
sf.skip_obmc_in_uniform_mv_field
sf.skip_wm_in_uniform_mv_field

If both features are turned on, at speed 0
Compression performance loss: 0.059% midres, 0.021% lowres
Speed up: ~1%
