Reintroduce struct definitions for mlk_poly{mat,vec}

[hanno-becker]

• Change mlk_polyvec back to struct { mlk_poly vec[MLKEM_K]; }
• Change mlk_polymat to struct { mlk_polyvec vec[MLKEM_K]; }
• Update all function signatures to use pointer style
• Fix all implementations to use struct member access
• Update tests, benchmarks, and CBMC harnesses
• Add consistent const annotations

[hanno-becker]

The runtime of polyvec_add further degrades here to >6min. That should certainly be addressed before this PR can be merged.
