aria-avx512 implementation uses AVX512 and GFNI.
It supports 64way parallel processing.
So, byteslicing code is changed to support 64way parallel.
And it exports some aria-avx2 functions such as encrypt() and decrypt().
AVX and AVX2 have 16 registers.
They should use memory to store/load state because of lack of registers.
But AVX512 supports 32 registers.
So, it doesn't require store/load in the s-box layer.
It means that it can reduce overhead of store/load in the s-box layer.
Also code become much simpler.
