Restructure RecActsTracking for LCG 105 compatibility
requested to merge zhangyz/cepcsw-acts-upgrade:zhangyz/lcg105/recactstracking-restructured into master
Reorganize RecActsTracking code into ActsHelper/RecActsSvc/RecActsTracking subdirectories while preserving LCG 105 API compatibility:
- ACTS v35: PluginTGeo, old include paths, old type names
- EDM4hep 0.x: TrackerHitCollection, MCRecoTrackerAssociationCollection
- Gaudi: GaudiAlg/GaudiAlgorithm.h, GaudiAlgorithm base class
RecActsTracking remains commented out in Reconstruction/CMakeLists.txt.
