- Use a PRD-to-track map rather than the PRD_AssociationTool which conains a PRD-to-track map
  internally. This is needed to resolve ATLASRECTS-5005.
- Made all methods const.
- The score processor does not create track copies anymore, thus PRD-to-track maps stay valid for
  scored tracks.
- The ambiguity processors now use a helper class which manages the new and original tracks i.e.
  tracks with mixed ownership, and creates track copies only for the final track collection if
  necessary.
- Moved debug ntuple code of simple ambiguity processor to a new derived class, to improve the
  readability.
