x86_64: Add avx2 optimized __memcmpeq in memcmpeq-avx2.S
No bug. This commit adds new optimized __memcmpeq implementation for avx2. The primary optimizations are: 1) skipping the logic to find the difference of the first mismatched byte. 2) not updating src/dst addresses as the non-equals logic does not need to be reused by different areas.
