Do you need this change? If I understand correctly, PermissionServicePtr is a
InterfacePtr<PermissionService> and that has an empty dtor. Doesn't that mean
the GC doesn't need to be Finalized?

InterfacePtr's destructor is non-trivial as it destroys the
internal::InterfacePtrState which is what closes the Mojo pipe.
