Support setting the _PROFILES app-op

Add public broadcast
CrossProfileApps#ACTION_CAN_INTERACT_ACROSS_PROFILES_CHANGED =
"android.content.pm.action.CAN_INTERACT_ACROSS_PROFILES_CHANGED" and
hidden API CrossProfile#setInteractAcrossProfilesAppOp.

This new hidden API should be used rather than setting the app-op
directly. It ensures that the app-op is set for each user in the profile
group and that the new broadcast is sent when an app's ability to
interact across profiles has changed.

Unit tests are added alongside these changes. CTSVerifier changes should
be subsequently added to enforce the behaviour of the new public
broadcast.
