Apply package visibility to LauncherApps.Callback

Applications could know package related events via registering and
implementing the LaunchersApps.Callback. We should also apply the
visibility to LauncherApps.Callback like what we did for Broadcast-
Receiver.

For removed one, using a new protected broadcast with the visibility
allow list in the extra instead since the PackageSetting is already
deleted and wouldn't be able to get its visibility allow list.
