Add binding support for sensor readings

Many of the sensors' QML "reading" value properties change with high
frequency. This makes them candidates to benefit from the more
performant bindable support.

This commit adds the bindable support for QML sensor 'reading' classes:
pressure, gyroscope, tap, compass, proximity, orientation, distance,
magnetometer, lid reading, tilt, rotation, humidity, holster, ambient
temperature, light sensor, altimeter, IR proximity, accelerometer,
ambient light, and sensor reading baseclass (timestamp common to all)

In addition to the 'reading' classes, the commit adds bindable support
for QmlSensor::reading, as it's change signal is emitted with high
frequency, on every sensor reading change.
