New kernel drivers and device implementation updates (#561)

- Added modular device support and devicetree bindings for ILI9341, ILI9488, CST816S, XPT2046, and GPIO button input, updating several board configurations for display/touch/backlight/keyboard/battery. - Added a setting to control deprecated HAL usage (device property + Kconfig).

+  GPIO button(s) that emulate UI navigation keys, for boards with only 1 or 2 physical
+  buttons instead of a full keyboard or touchscreen. Exposes a KEYBOARD_TYPE device: each
+  button's short/long press is translated to an LVGL navigation key, decided once the
+  button is released (so a long press is only recognized after release, matching how long
+  a button was actually held).
