Introduce brillo binder interface
This is more or less an exact analogue of the DBus interface, but
available over binder. We also add support to the client library and let
update_engine_client build with binder. We don't yet support an
equivalent of the status signal/the HandleStatusUpdate method. That will
come in a future CL.
