The new CI has four stages:
1. **pretest** jobs are run automatically as a first check
2. **test** jobs run at each commit but contain only a limited number of configurations
3. **merge_request** these jobs need to be run **manually** before merging a merge request
4. **benchmark** benchmarks are only run manually if needed

274e09cd introduced a skip of the generation if the target file is not
present. While this might hint a wrong target directory it also prevents the
generation of new files. Since the provided mesa_pd.py script asks to
confirm the target directory anyway, this skip is removed.

Since some benchmarks/tutorials are registered as tests they have to be
built in order to run.
