…ulting bool later

- Remove string comparisons
- Remove copying of ValueMaps
- Tidy up monitoring implementation

Using the same ValueMap for all input track collections works for
track validation, as all input collections are Refs to the original
generalTracks.

- Break as soon as know that the return value is false
- Reorder tests such that lighter ones are checked first
- Reduce repeated calculations (minor)

Reduce repeated computations in
- MTVHistoProducerAlgoForTracker::fill_simAssociated_recoTrack_histos()
- MTVHistoProducerAlgoForTracker::fill_generic_recoTrack_histos()
- MTVHistoProducerAlgoForTracker::fill_ResoAndPull_recoTrack_histos()

Streamline MTVHistoProducerAlgoForTracker::fill_generic_recoTrack_histos(),
plus other cleanups.

This reduces the amount of repeated calculations of those. Eliminating
all repeated calculations would require fancier caching, or
precalculating them for all TPs (such that they would be accessible
through Refs, taking into account that label_tp_effic and
label_tp_fake may point to different TP collections...).
