DQM/SiTrackerPhase2: Streamline and clean up DQM code

[brandiskip]

PR description:

Used existing helper functions in TrackerPhase2DQMUtil.cc (with declarations in TrackerPhase2DQMUtil.h) to reduce redundancy in bookHistograms and added new helper functions for fillDescriptions across the following files:

• Phase2OTMonitorTTCluster.cc
• Phase2OTMonitorTTStub.cc
• Phase2OTMonitorTTTrack.cc

Renamed histogram Track_LQ_Eta_ECStubs to Track_All_Eta_ECStubs to correct the naming convention.

Updated x-axis range and binning for d0 histograms to match range found in Validation package.

Removed magic numbers for the number of discs in Phase2OTMonitorTTStub.cc, replacing them with a call to Settings.h.

The updated DQM output ROOT file can be reviewed here.

Updated histograms in the following DQM folders:

• TrackerPhase2OTL1Track
• TrackerPhase2OTStub
• TrackerPhase2TTCluster
