Original issue's description:
> Device Orientation API on Chrome OS
>
> Implement DataFetcherSharedMemory on Chrome OS to provide Device Orientation support. Create SensorManagerChromeOS to observe accelerometer events, and to generate updates to the Device Orientation API.
>
> This is a follow up to: https://codereview.chromium.org/680383007/
>
> With the accelerometer on Chrome OS now exposed to content/ from chromeos/accelerometer, no ash/ implementation is required. No public api in content/public/browser is needed either.
>
> TEST=SensorManagerTest.OrientationBuffer, SensorManagerTest.NeutralOrientation, SensorManagerTest.UpsideDown, SensorManagerTest.BeforeUpsideDownBoundary, SensorManagerTest.LeftEdge, SensorManagerTest.RightEdge, SensorManagerTest.BeforeRightEdgeBoundary
