Ken Van Hoeylandt d8346998ce
Merge develop into main (#368)
New boards:
- LilyGO T-Dongle S3
- M5Stack StickC Plus
- M5Stack StickC Plus2

New drivers:
- AXP192: power control via I2C
- ButtonControl: GPIO button input as LVGL device

Other changes:
- Updated implementation of AXP192 driver for Core2 board
- Fix launcher UX for vertical layout
- Fix error when properties file had an empty line
- Add `__floatsidf` to `tt_init.cpp`
