Chloe Bethel d494c23a88 Enable telemetry and I2C sensors on STM32WL (except accelerometers) (#7008)
* Update platformio inis for stm32 platform and wio-e5 variant for enabling i2c

* Don't reference timezone functions if MESHTASTIC_EXCLUDE_TZ is defined

* Use custom pow_of_two in RadioInterface instead of floating-point pow()

* First pass: enable sensors for STM32wL

* Fix AirQualityTelemetryModule being created if the PM25AQI header is missing

* Link in power sensor libraries

* more ini tweaks

* Add =1 to EXCLUDE defines, fix indentation.

* Drop HAS_WIRE in ini, it's defined in architecture.h

* Fix build when power sensor libraries are missing

Make MAX sensor integration into Power.cpp optional based on its library header existing.
Also make NullSensor expose a voltage and current sensor, because Power calls directly into these for INA sensors.
This lets us remove all the deps for the STM32WL platform.

* Change default I2C for RAK3172 to be I2C1, not I2C2

* Respect the laws of mathematics (oops)
