When Flutter engine connects to Scenic, Scenic has already checked the display and graphics device availability before Scenic starts; so it is guaranteed that display devices are available and surface is valid when it is created. Thus this change removes the device watching details from flutter surface on Fuchsia so that it doesn't need to do duplicated checks and hides the device-specific details.
