Add tof v21j mCBM + creation macro: some fixes to modules positions by TOF experts

Please insert x between square brackets to tick the boxes, add a meaningful description if the title is not enough and check the outcome with the "Preview" tab

In case you committed a new geometry:

• Ran the scripts for materials and radiation length check on my new geometry file? (and read carefully the output of course)

  bash ci_scripts/check_radlen.sh <path>/<file>.geo.root

• Added also the corresponding creation macro?
• Checked that the geometry does not contains unexpected overlaps, e.g. either at end of the creation macro or with the something similar to the mCBM macro
  macro/mcbm/mcbm_check_overlaps.C

Linked to cbmroot_parameter!131 (merged) and cbmroot_input!37 (merged).

Should be merged at the same time after approval of all 3 and be followed by update of Cbmroot external hashes
