Revive and reimplement PrDebugTrackingLosses

The algorithm to study particle trajectories not found and reconstructed by the pattern recognition was (rightfully) removed in !3381 (merged). The idea behind this algorithm is reimplemented and enhanced to ease track reconstruction developments.

Code duplication is avoided by outsourcing some PrChecker code into a header which is moved to PrKernel. This way, reconstructiblity and and particle type definitions can be reused elsewhere, e.g. in the cheated PR algorithms.

Options and test provided in Moore!2343 (merged)
