Create track summaryies together with tracks and finish migration of PRD association.
requested to merge goetz/athena:TrackSummary_master_create_summary_when_creating_track_deprecate_PRD_asso_tool into master
This set of commits fixes the remaining main issues in the ID track reconstruction which prevent running athenaMT with more than one thread.
Changes:
- replace remaining usage of the PRD association tool by the external PRD to track map plus the helper tool;
- avoid creation of track summaries on demand but create summaries before tracks are recorded in storegate;
- made TRT exntesion tool private, since it keeps an internal event state;
- restored track statistics gathering in ambiguity resolver (which was removed when restoring the the split cluster map handling from r21, which was removed in master).
