Make PackageManager#arePermissionsIndividuallyControlled system-api

The PermissonController is going to become a mainline module, hence it
has to compile against @SystemApi.

PackageManager#arePermissionsIndividuallyControlled controls how certain
permissions are presented in the UI, hence Permission controller needs
to read it. The value of this API comes from a config option.
