[DeviceLight] Add renderer+common parts
Adding the Renderer and Common part in the content side for the DeviceLight API.
Add Unit tests for deviceLight pump
Add DeviceLight support in renderer_webkitplatformsupport_impl.h|cc
The default polling time interval of DeviceLightEventPump
is right now set as of 200 milliseconds.
(device motion/orientation = 50ms)
In Firefox (Android) implementation, DeviceLight's frequency of
update is set as SensorManager.SENSOR_DELAY_NORMAL which in Android
parlance translates to 200 milliseconds delay which is 5 times a second.
Ofcourse the delay is only a suggested delay, system typically uses a
smaller delay.
