SystemUI: write keyguard enabled setting to CMSettings

Instead of saving this to a shared preference in SystemUI, let's
leverage the CM SDK Settings Provider so we can query this state and let
the user know why the keyguard is disabled.

Also move the logic into KeyguardViewMediator to monitor the state
change and apply it locally.
