Reduce RF_PROTO_OFF logic, disable R9M Sport out when internal telemetry is on (#5159)

* Remove most of the special logic associated with RF_PROTO_OFF

This simplifies code in many areas since the internal module does not require special handling and also fixes a few bugs with INTERNAL_PPM

* Disable R9M sport option if internal module has telemetry

* Fix X12s build

* Use macros instead of direct comparisions

* Fix sport bit sent the wrong way. Rename S.port out to Telemetry

* Compile fix
