Be more strict about triggering notification lights

Don't trigger lights if they should be suppressed by notification flags.

Don't log that notification lights happened if global or temporary
settings have turned them off

Test: runtest systemui-notification, verify
notification_itnerruptiveness numbers for a fresh 3p app that uses
lights
