Title: Cluster Charge Cut rework

Major rework of Cluster Charge Cut.
1) CCC infrastructure moved in a common place
2) factorized the Chi2ChargeMeasurementEstimator in a pre filter based on CCC (and later on to Cluster shape) and chi2
3) major cleanup of TrackClusterRemover
4) added a specific producer for ClusterChargeCut masking
5) minor cleanup and optimization here and there
6) pre filter mono hits before matching

Minor regressions achieved despite the large number of changes.
A more consistent approach will then be developed which will affect reco performances

pre filter mono hits before matching give as a 20% speedup (40PU, 25ns) in pattern recognition
