20948 compass support (#6707)

* Add __has_include blocks for sensors

* Put BMP and BME back in the right sensors

* Split environmental_base to environmental_extra, to compile the working sensor libs for Native

* Remove hard-coded checks for ARCH_PORTDUINO

* Un-clobber bmx160

* Move BusIO to environmental_extra due to Armv7 compile error

* Move to forked BusIO for the moment

* Switch to Meshtastic ICM-20948 lib for Portduino support

* Use 20948 for compass direction

* Compass is more than just RAK4631

* Cleanup for 20948 compass

* use Meshtastic branch of 20948 lib

* Check for HAS_SCREEN for showing calibration screen

* No accelerometerThread on STM32
