[PWGDQ] Add processPbPbWithFilterBarrelOnlyWithFIT for UPC analysis with FIT detector info

- Created new process function using gkEventFillMapWithMultsRapidityGapFilterZdcFit
- This enables ReducedFit table filling for UPC Pb-Pb analysis
- Fixes segmentation fault caused by unfilled FIT table during framework shutdown
