* [CI] Improve checks

- Adds testing for variants of features so changes that break feature
sets like disabling games can be caught
- Adds more of the CI tests to pre-commit
* [CI] Add more feature sets to test
* [CI] Check github actions before comitting
Requires act: https://github.com/nektos/act
* [CI] Add caching between builds
* [CI] Add caching everywhere
* [CI] Add more feature tests
* [CI] Add YAML schemas
* [CI] Disable audit when running locally
This is needed because the audit action requires a GITHUB_TOKEN which we
don't have when running locally.

Using actions-rs/clippy-check means that PRs will problems will
automatically have the relevant lines annotated
