chore(cpn): Allow configuring AUX serial port as "External module" (#2854)

* Add external module to hardware settings

* Use serial port aux1 rather than radio profile externalaccessmod
Move module conversion function from OpenTxFirmare to ModuleData

* Remove externalaccessmod from radio profile options

* Unnecessary CMake option HARDWARE_EXTERNAL_ACCESS_MOD removed.
