Callback the surface package after the views are drawn locally

* SurfaceControlViewHost#setView() method will post a task to the
  main thread to draw the view. We want to callback the surface
  package to the remote process after the view is drawn and ready
  to be shown, to avoid the flicker when the remote process attaches
  it to their window when it's not drawn.
