device orientation: Ensure new reading values are available in tests.

Several tests in external/wpt/orientation-event/ have been flaky, especially
the Device Orientation ones.

The Device Orientation spec implementation in Blink uses its own timer at
60Hz to read from the shared memory buffer updated by the platform sensors,
rather than relying on OnSensorReadingChanged() being called by the platform
side. The MockSensor implementation in WPT uses window.setInterval() to
update the shared memory buffer and simulate a real platform sensor.

For some reason, the Mac bots in particular seem to cause those two timers
to get out of sync quite often, in which case the Device Orientation
implementation might end up reading an older value even though a test has
already called setMock{Motion,Orientation}Data() again.

Fix it by adding a workaround: in the Device Orientation tests (but not the
Generic Sensors ones), we immediately update the shared memory buffer when
changing a mock sensor's reading so that the value will always be available
to the Device Orientation code.
