Touch and display driver subsystems reworked (and more) (#302)

- Refactored `TouchDevice`: it can now start/stop LVGL separately, and it has an optional `TouchDriver` interface - Refactored `DisplayDevice`: it can now start/stop LVGL separately, and it has an optional `DisplayDriver` interface - Updated all boards and drivers for above changes - LVGL can now be stopped and (re)started on the fly - Fixed issues with restarting Gui and Statusbar services - Refactored `Gui` service to be class and renamed `Gui` to `GuiService` - Fixed `Statusbar` service: forgot to deregister one of the icons - Updated `esp_lcd_st7701` to v1.1.3 - `lv_textarea_create()` now automatically registers the hardware keyboard hooks (by wrapping the function) - Fixed and updated `tactility.py` - Cleanup of a lot of code - `BootInitLvglBegin` and `BootInitLvglEnd` are replaced by `LvglStarted` and `LvglStopped`. - Introduced `tt::service::State` which is accessible via `tt::service::getState()` (and internally via `ServiceInstance`) - Started replacing `#define TAG` with `constexpr auto TAG = "..";`
