Distinguish between settings which are permanently unavailable on
the device, and temporarily unavailable. This enables us to restrict
which setting slices are exposed in onSliceGetDescendants.
The primary changes in this CL are renaming:
"DISABLED_UNSUPPORTED" -> "UNSUPPORTED_ON_DEVICE"
to be more clear the the setting will cannot be accessed on the device, and,
adding a new enum to encapsulate settings which are currently unavailable, but
could be enabled in the future.
Also remove UNAVAILABLE_UNKNOWN. Devs should never need this enum.

APP_STANDBY_ENABLED is controlled by server side to do experiment.
Before this CL, Adaptive Battery is hooked up to this flag, so
even though if user turns it off, it may be turned on by server.
Add a high level ADAPTIVE_BATTERY_MANAGEMENT_ENABLED to control
the feature in settings UI side.
