AVX2 implementation of 4-tap filter

Added AVX2 implementation of aom_filter_block1d16_h4_avx2
and aom_filter_block1d16_v4_avx2 for block width >= 16.
Approximately 30% improvement is seen w.r.t 8-tap filter
at unit test level. When tested for 10 frames of parkrun
720p50 content with speed=1 preset, 0.5% encode time
reduction is seen.
