refactor CUDA versions in dependencies.yaml (#4084)

Contributes to rapidsai/build-planning#7.

Proposes splitting the `cuda-version` dependency in `dependencies.yaml` out to its own thing, separate from the bits of the CUDA Toolkit this project needs.

### Benefits of this change

* prevents accidental inclusion of multiple `cuda-version` version in environments
* reduces update effort (via enabling more use of globs like `"12.*"`)
* improves the chance that errors like "`conda` recipe is missing a dependency" are caught in CI
