Add AVX2 optimization for cross_correlation module

Added compute_cross_correlation avx2 function and changed
test_bench to support AVX2 version.

Module level gains improved by a factor of ~1.45
on average w.r.t to SSE4_1 modules.

When tested for multiple test cases observed 0.4%
average reduction in encoder time for speed = 1 preset.
