Moving common getRegion and StrawGasType methods to be helper functions

Multiple classes in TRT_Digitization implement identical getRegion and StrawGasType methods. In order to avoid repeated code, these methods have been extracted to be helper functions in a TRTDigiHelper namespace. The StrawGasType method has been adapted to use MsgStream, to make the output clearer when running in AthenaMT.
