Add common utilities for CRYSTALS Kyber/Dilithium

Most notably, this is an abstract implementation to handle CRYSTALS polynomials, poly vectors and poly matrices. Also, a generic implementation for bit-packed encoding/decoding of coefficients useful for both Kyber and Dilithium. Co-Authored-By: Fabian Albert <[email protected]>
