MuonReadoutGeometry write sensitive detectors for Rpcs

Johannes Junggeburth requested to merge jojungge/athena:RpcSensitive into main

Hi everybody,

this MR adds the sensitive detector class to write xAOD::SimHits from the Rpcs using the new ReadOutGeometry. Hits passed by Geant4 are propagated to the center of the gasgap. The volume hierachy is traversed to fetch the corresponding detector element from the volume name. If that's successful, the hit is expressed in the local coordinate system of the first gas gap to determine the rpc phi panel and the gas gap along Z. The gasgap Identifier is then saved as the Identifier of the RPC sim hit. The charge splitting onto the eta & phi strips + the strip identification will be perfomed at the digitization stage.
