T-Beam refactor

There is a lot to this PR, so if there are any questions let me know.

The idea here is to merge T-Beam fw so that there is less redundant code. Most versions (except the 0.7) share PMU code, init sequence, and most IO pin definitions.

- Merged all T-Beam board.h files into one TBeamBoard.
- Added PMU code to identify different AXP chips.
- Modified "lilygo tbeam SX1276" variant to cover all T-Beam SX1276 versions
- Modified "lilygo tbeam SX1262" variant to cover all T-Beam SX1262 versions
- Enabled GPS on all T-Beam versions/models
- Enabled BME280 on the Supreme

I am also updating EnvironmentSensorManager to allow for boards that do or don't have GPS enable pins, as well as a PERSISTANT_GPS define check for boards that want GPS to stay active after boot.
