x86: Add TARGET_AVX256_[MOVE|STORE]_BY_PIECES
1. Add TARGET_AVX256_MOVE_BY_PIECES to perform move by-pieces operation
with 256-bit AVX instructions.
2. Add TARGET_AVX256_STORE_BY_PIECES to perform move and store by-pieces
operations with 256-bit AVX instructions.
They are enabled only for Intel Alder Lake and Intel processors with
AVX512.
