Query the uid process state in opChanged instead of relying on callbacks.
Occasionally, Android may enter a state where onUidStateChanged arrives
late or not at all until another process state change occurs. In some
situations that may mean isUidVisible is (incorrectly) false when the
app is in the foreground. Instead of relying on the onUidStateChanged
callback, query the state directly through activity manager.
The flag protecting this is only needed while data_delivery_permission_checks
is not flipped, and can be removed if that advances first.
