Support for mcbm MVD detector. Builds on commit by @ajit.kumar
The mCBM MVD detector unlike in main CBM, is not inside the pipe vacuum but instead is inside the cave behind the STS box.
Intended to allow the standard transport, digi, reco, and qa macros working.
Corresponding mMVD binary is contained in CbmSoft/cbmroot_geometry!310 (merged)
