avfilter/x86/scene_sad: add AVX512 implementation
Trivial to add, but a lot faster (on my machine).

scene_sad8_c:                                       114476.4 ( 1.00x)
scene_sad8_sse2:                                      8644.3 (13.24x)
scene_sad8_avx2:                                      4520.1 (25.33x)
scene_sad8_avx512:                                    3153.0 (36.31x)
