TRD-DigitTask Simplified histogram view by merging ~ 180 plots onto 39 canvases (#1736)

* Simplified histogram view by merging ~ 180 plots onto 39 canvases

* I have moved  mClusterAmplitudeChamber out of curly brace also corrected the name of amplitude

* clang

* removed  mNClsAmp and added histo for cluster per layer

* clang-format
