Add Firefox versions for DeviceMotionEventRotationRate API (#13018)
Add Firefox versions for DeviceMotionEventRotationRate API (#13018)

This PR adds real values for Firefox and Firefox Android for the `DeviceMotionEventRotationRate` API.  There's no indication in Firefox's IDL (https://searchfox.org/mozilla-central/source/dom/webidl/DeviceMotionEvent.webidl) that the `DeviceMotionEvent` interface requires a secure context.
