ARROW-8401: [C++] Add byte-stream-split AVX2/AVX512 implementation For decode, similar implementation with the SSE version for both AVX512 and AVX2. For encode, float path implemented for AVX2/AVX512 also double for AVX512. AVX2 double fall back to SSE as currently no epi16 permute support. BM_ByteStreamSplit result reach up to 3x for AVX512, 2x for AVX2.
