In the past, we allowed non system overlays on user-debug rom.
Acoording to the user-debug guildline, we should not have differnt
behavior between the user build and user debug rom.
To maintain the consistency between user and user debug rom,
We're creating a new developer setting for allowing non-system overlay on
Settings. By default, we don't allow any non-system app overlays on
Settings app unless user turns it on explictly.
Test: Run robotest. Turn on setting, see the overlays on Settings.
Turn off setting, do not see the overlays on Settings.
