Add DeviceProximityController to support Device Proximity Events.

https://bugs.webkit.org/show_bug.cgi?id=97630

Reviewed by Hajime Morita.

Source/WebCore:

Implement DeviceProximityController which is inherited from DeviceController to support Device Proximity Events.
DeviceProximityController has two major functionalities.
- When listener is added, DeviceProximityController stores DOMWindow pointer to m_listeners
  and start gathering proximity event.
- When DeviceProximityController receives a proximity event from client, fire an event using m_listeners.
In addition, setDeviceProximity function is added to Internals for layout test.
