New kernel drivers and more (#560)

- Added kernel base drivers for: display, pointer (touch, mouse, etc.), keyboard, adc, power supply and backlight
- Implement new kernel driver modules: `st7789-module` and `gt911-module`
- Implement ESP32 ADC "oneshot" kernel driver
- Implement ESP32  backlight kernel driver with ledc API
- Implemented `battery-sense` driver that allows for voltage measurement and creates a power supply child device
- Updated github actions
- Updated flash scripts
- Fix for esp32 legacy driver conflict with ADC
- Created separate `lilygo-tdeck` and `lilygo-tdeck-plus` devices
- Created `lilygo-module` with LilyGO kernel drivers
- Fix for intermittent errors in build related to code generation of `devicetree.c`
- `lvgl-module` can now map kernel drivers onto LVGL devices
- Created `KernelDisplayApp` as a mirror of `HalDisplayApp` (formerly `DisplayApp`)
- Removed `struct` and `enum` prefix in a lot of kernel driver cpp source files
- `lilygo-tdeck` and `lilygo-tdeck-plus` are now fully relying on kernel drivers and don't use any of the old HAL
