Initial prerequisite for #112. Adds a `module-lattice` crate intended for sharing functionality between `ml-kem` and `ml-dsa`. The crate is an extraction of the `ml-dsa` crate's `module_lattice` module (already designed for this purpose), and has been extracted as of this commit: RustCrypto/signatures@942de7f Several types/methods were made `pub` in order to be usable in this capacity. This commit doesn't actually try to use `module-lattice` in conjunction with `ml-kem`, rather it just extracts the functionality from `ml-dsa`. However, having this crate in-repo with `ml-kem` should help simplify wiring it up. A code comment in `lib.rs` notes there are currently almost no tests(!) which seems problematic, although it tends to be our typical problem with crates like this where they're designed to be abstract and you need something concrete to test against. It suggests moving the actual field definitions to that crate and testing against those, which seems like a reasonable next step. Perhaps we can find a way to integration test PRs against `ml-dsa` as well (or at least ensure it still builds), using a special testing project with `patch.crates-io` directives.

We can share code between `ml-kem` and `ml-dsa`, and the previous `ml_dsa::module_lattice` submodule was designed so it could be extracted and shared with `ml-kem`. That just happened in RustCrypto/KEMs#199, which pulled the `module_lattice` module out of this crate at 942de7f and extracted it into its own crate, which is now published as `module-lattice` v0.1.0-pre.0. This removes the previous `module_lattice` module and switches to the new crate. See also: RustCrypto/KEMs#112
