Rework V0Finder, fix BPHY10 crash
This is quite a big MR but it ends up fixing multiple problems:
- Reworks/refactors V0Finder to reuse decorator code
- Fix a bug in BPHY10 (ATLBPHYS-235) - The change to
JpsiPlusV0Cascade.cxx - Fixes V0Finder erroneously decorating the primary vertices (ATLASRECTS-7186)
- Clean up old dependencies
- Use xAOD::EventInfo instead of BeamSpotConditions
