Add Run 4 workflow tests

Add Run 4 workflow tests to be included in the CI. By default this runs a G4 simulation job followed by a digitisation+reco (RAWtoALL) chain using the simulation output from the previous step. For this reason the two tests can not run in parallel (but independently they can using fixed inputs).

File comparisons are disabled for now as things change very often. Performance checks are also disabled as they need to be adapted for CA-based config (FYI @amete).

The goal is to enable this in the CI ASAP to avoid Run 4 setup to be broken as it was happening recently. 10 single muon events run ~6 min on my (relatively new) machine. In the future we will change the input to cover HGTD better, but for now let's keep it simple.
