Reduce cost of a11y services with magnification. Services that declare that they can control magnification, but never actually make a change or register a listener waste cycles as we compute magnification data they never use. Avoid registering for magnification callbacks unless magnification gestures are enabled, a service is listening for magnification changes, or a service has changed magnification.
