QTouch Group A/B method Disable and Re-enable Sensor for UC3L

The touch_qt_sensor_disable and touch_qt_sensor_reenable API can be used for Disabling and Re-enabling of QTouch Group A and Group B Sensors.  In order to Disable or re-enable a sensor, the API must be called with the corresponding sensor_id.  Disabling a Sensor disables the measurement process on all the Touch Channels corresponding to Sensor.

When a QTouch Sensor is Disabled or re-enabled, it is mandatory to force Calibration on all Sensors.  The Calibration of all Sensors is done using the touch_qt_sensors_calibrate API.
