Patch adds AMD64 AVX512-FMA52 implementation for Poly1305.
Benchmark on Intel Core i3-1115G4 (tigerlake):
Before:
| nanosecs/byte mebibytes/sec cycles/byte auto Mhz
POLY1305 | 0.306 ns/B 3117 MiB/s 1.25 c/B 4090
After (5.0x faster):
| nanosecs/byte mebibytes/sec cycles/byte auto Mhz
POLY1305 | 0.061 ns/B 15699 MiB/s 0.249 c/B 4095±3
