capcom/cps2.cpp: Support for CPS2 debug DIP switches (#11540)

Browse Source 
* initial working version

* fixed incorrect mapping in memory by using a custom read handler; cleaned up unnecessary port conditions; better comments

* moved read handler directly into the map segment; renamed hardware type device tag

* corrected accidentally moved line break

* switched from native array usage to optional_ioport_array
