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`
