22.0-bugfix-TrkAmbiguityProcessor

This fixes a bug in the event counting in AmbiCounter.icc by removing the 'all' category of the counters and fixing the eta bounds dimension to four (barrel, transition, endcap and 'forward'). The 'all' category statistics are now calculated on-the-fly by summing the regions using std::accumulate. Changes were made to clients to ensure the eta bounds inputs are the correct size. Other changes (formatting, principally) were incidental to the debugging.
