rework sensor instantiation to saves memory by removing the static allocation (#8054)

Browse Source 
* rework I2C sensor init

the goal is to only instantiate sensors that are pressend to save memory.
side effacts:
 - easyer sensor integration (less C&P code)
 - nodeTelemetrySensorsMap can be removed when all devices are migrated

* add missing ifdef

* refactor a bunch of more sensors

RAM -816
Flash -916

* fix build for t1000

* refactor more sensors

RAM -192
Flash -60

* improve error handling

Flash -112

* fix build

* fix build

* fix IndicatorSensor

* fix tracker-t1000-e build

not sure what magic is used but it works
