       NotificationManager: Concentrate LED light capabilities in a single location

       We have a bunch of individual boolean toggles for various LED behaviors
       and combinations, which end up getting used as a similarly sprawling bunch
       of getResource() calls across various locations. And they keep piling up...

       So... create a new overlayable bit field of LED capabilities,
       config_deviceLightCapabilities, where we can throw everything
       and expand in the future. Remove the obsolete overlays so that
       everyone uses the new overlay moving forward.
