Changes StreamClientConnection to use an IPC::Connection::Client rather than MessageReceiver for providing
callbacks to the consumer.

Converts RemoteRenderingBackendProxy and RemoteGraphicsContextGLProxy to use their StreamClientConnection to receive
notifications about the GPU process crashing from their StreamClientConnections rather than their GPUProcessConnection.

Makes RemoteRenderingBackendProxy create its StreamClientConnection using the provided SerialFunctionDispatcher, so that
we can send and receive all messages from that.
