Original change's description:
> [Background Fetch] Move all updatable UI options to their own proto.
>
> Bundle up the icon and the title since they will be accessed/modified
> together in the updateUI call.
>
> It also makes sense to move the icon from the metadata proto since that
> will speed up getting the registration info.
