Add an event command to calibrate the touch screen

Add an event command to calibrate the touch screen of the HMI device. The
Calibrate Touch Screen
command displays a red target on the screen of the HMI device. At runtime, press and hold the center of the target until the target turns white and another red target appears. Continue pressing and holding the centers of all remaining targets as they appear. All processed targets are replaced with white targets. A green circle with a check indicates a successful calibration.
A red circle with an X indicates a failed calibration. If a red circle with an X appears, perform the event again to calibrate the screen.
