Improve the performance of the CI jobs

- Run the project checks in parallel
  This should speed up CI by running the checks at the same time.
  It doesn't give the possible 5x improvement because of the limited CI resources.
- Add npm cache to Github action cache
  As well as caching node_modules we now also cache `~/.npm`, which will speed up cases where the dependencies have changed.
- Run tests independently of other checks
- Use incremental TS builds when type checking
- Use eslint cache
