Include timing information in strip digitization by default. It seems it improves tracking performance for pile-up jobs, especially in case of overlay. May fix ATLITKSW-192.
I ran 10 event validation and it looks much better now: https://www.desy.de/~tadej/upgrade/PhysVal/20221114_overlay_ttbar/
Note that we do not expect perfect agreement and probably there are still other things that would have to be improved. I will try to run larger validation to smoothen-out statistical fluctuations.
