Drivers, device migrations and other improvements (#566)

- RGB display driver added
- display_driver API:
  - Added software-based display rotation for screens without hardware rotation support.
  - Improved display capability detection across supported display drivers.
- lvgl_display driver:
  - Improved framebuffer handling for smoother, more reliable display updates.
  - Display gap and rotation behavior now adapts more accurately to hardware capabilities.
- Migration Crowpanel 5" basic & advance to kernel drivers
- Improve KernelDisplay app: brightness controls are hidden for displays that only support on/off operation
- device.py now allows for (non-ambiguous) partial device IDs
- TactilityKernel: Implement more tests
