…nEvent's absolute value on error, a=testonly

Automatic update from web-platform-tests
orientation-event: Test DeviceOrientationEvent's absolute value on error (#44557)

Test for w3c/deviceorientation#139. When a reading
cannot be provided, `absolute` needs to be set accordingly depending on the
event type we are listening to.
