Fix geometry of the TRD system in the mCBM 2021
The current modification provides :
- correct order of TRD modules according to layers
- related code modification (due to hard-codded module number)
- re-generated set of parameters for the geometry CbmSoft/cbmroot_parameter!48 (merged)
- correct ON/OFF switch mechanism for the TRD layers to study material burdget issues
