RFR: 8325991: Accelerate Poly1305 on x86_64 using AVX2 instructions [v12]

[Srinivas Vamsi Parasa]

> The goal of this PR is to accelerate the Poly1305 algorithm using AVX2 instructions (including IFMA) for x86_64 CPUs.
> 
> This implementation is directly based on the AVX2 Poly1305 hash computation as implemented in Intel(R) Multi-Buffer Crypto for IPsec Library (url: https://github.com/intel/intel-ipsec-mb/blob/main/lib/avx2_t3/poly_fma_avx2.asm)
> 
> This PR shows upto 19x speedup on buffer sizes of 1MB.
