lib/x86/adler32: add an AVX-512 implementation
libdeflate used to (before commit 416bac3) have an AVX512BW implementation of Adler-32, but I removed it due to AVX-512's downclocking issues. Since then, newer Intel and AMD CPUs have come out with better AVX-512 implementations, and these CPUs tend to have AVX512VNNI which includes a dot product instruction which is useful for Adler-32. Therefore, add an AVX512VNNI/AVX512BW implementation.
