Merge develop into main (#337)

- Implement `UiScale` in `hal::Configuration`: small screens with no touch can now opt for a more optimized experience (e.g. Cardputer, Waveshare 1.47, Waveshare 1.3", etc.)
- Fix for Cardputer UART configuration and added I2C configuration
- Fix for software keyboard bug in Gui
- Removed deprecated fields from `hal::Configuration`
- Updated the simulator devices to use the new HAL config
- add `bool tt::hal::hasDevice(Device::Type)`
- Cleanup of `AppList` app code
- Improve `Gpio` app for small screen devices
- Added various ESP32 GCC wrappers to wrap LVGL functions (with manipulations for small screen devices)
- Moved `Launcher` assets to `assets/` subfolder
- Optimized `Toolbar` for small screen devices
- Stop showing `system/` partition in `FileBrowser` because it's read-only and not very useful. Created `config::SHOW_SYSTEM_PARTITION` to override this behaviour.
- Hide apps when their required hardware isn't available (I2C, UART, PowerDevice)
- Fix for `CYD-2432S032C` DPI setting
