NotificationManager: Concentrate LED light capabilities at a single location

We had(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 array of LED capabilities (config_deviceLightCapabilities)
where we can throw everything (and expand in the future). Also, create a
helper to abstract usage of the old (multi-resource) and new (single resource
array) formats to avoid breaking any deployed devices.
