Create another native handle to make sure Registry.Unregister works fine.

This is much simpler solution with less code maintenance as derived classes do not have to call Registry.Unregister(this);.
Only BaseHandle class will be responsible for Registry.Register and Registry.UnRegister which is much simpler and symmetric solution.
The only drawback is that we have to create an extra native handle.
