Remove usages of AppPermissionActivity

Remove all uses of the AppPermissionActivity, except the legacy usage in
ManagePermissionsActivity. Ensure all permission notifications link to
the ManagePermissionsActivity, not the AppPermissionsActivity.
Deprecated the AppPermissionActivity.

Test: * Install TestDPC.
* Set TestDPC as Device Owner
* Find "Get/Set permissions policy" and toggle to "Auto accept"
* Get the BasicLocation app by checking out
  https://github.com/android/location-samples and building it from there.
* Install the app onto the device and start it.
* Click on notification
* Click on link at bottom of screen. Screen should not crash.
