crypto: x86/nhpoly1305 - add AVX2 accelerated NHPoly1305
Add a 64-bit AVX2 implementation of NHPoly1305, an ε-almost-∆-universal hash function used in the Adiantum encryption mode. For now, only the NH portion is actually AVX2-accelerated; the Poly1305 part is less performance-critical so is just implemented in C.
