21.9: Updating TrackClusterAssValidationITk

New features:

• Adding possibility to use eta dependent pt cuts
• Removing EtaDependentCutsSvc, but only configuring eta bins, clusters, and pt cuts
  • This allows to print them in the final tables
• Configuring a global pt cut (= max(NewTrackingCuts.minPT()))

Cleaning:

• Removing TRT variables
• Renaming DBM with FWD
