Combine test, example, and cli jobs for better caching

By running a single job, we only need to store one cache per OS. Since the jobs share large parts of the dependencies, the total cache size of our workflow becomes smaller. This makes cache eviction less likely (GitHub only keeps the newest 10GB of caches).
