[12.5.X] EMTF DQM fix to remove duplicate x-axis bin labels

[mmusich]

resolves #39936

PR description:

Changed DQM plot neighbor labels to avoid duplicates. This meant relabeling DQM plots such as cscDQMOccupancy among others. Chambers with the label "N" became labeled "N1", "N2" ... depending on which sector they preceded.

Change implemented in response to #39936, in which it was discovered that histogram merging is dependent on bin labels in newer ROOT versions, and therefore cannot be duplicate (#25569)

The flag gemChamberBXVFAT.CanExtend was also set to false for consistency with other plots.

PR validation:

First, the issue outlined in #39936 was recreated using the PSet in /afs/cern.ch/user/c/cmst0/public/PausedJobs/HIReplay2022/job_244/job/WMTaskSpace/cmsRun1. Then, the plot labels were changed and new DQMIO files were made with DQMRootOutputModule. These files substituted the input files used in #39936 and the merge was successful.

ROOT files were also created using DQMFileSaverPB to view the plots and ensure that the labels were correct.

This change will also be backported to release CMSSW_12_5_X and 12_5_1_patch1,
