Clean up arguments for subpel_search

The constant parameters for fractional_mv_step_fp are now stored in a
separate struct SUBPEL_MOTION_SEARCH_PARAMS, which contains two
additional structs: SUBPEL_SEARCH_VARIANCE_PARAMS and MV_COST_PARAMS.

The former contains the parameters needed to compute the variance, and
the latter contains parameters for computing the mv_cost.
