Replace usages of device::OrientationData with DeviceOrientationData

Since DeviceOrientationData class has all the information from
device::OrientationData, and DeviceOrientationEventPump is now in blink,
DeviceOrientationData is now passed to DeviceOrientationDispatcher.
device::OrientationData will be removed in a subsequent change.
