Refactor weight calculation code in apply_temporal_filter()

In apply_temporal_filter(), few of the variables related to
weight calculation were calculated for every pixel though
they are constant at sub-block level. In this CL, the
relevant calculations are done beforehand and the same are
consumed based on the sub-block index in both SSE2 and AVX2
variants of the function.
