I exposed this so that I could call it from RenderFrameProxy.  I thought about
having the proxy directly call setFocused() through WebWidget, but the plugin
notifications below seemed important to do also.  I'm assuming that if an OOPIF
hosts a plugin, that plugin should get recorded in the swapped-out RV (e.g., in
active_pepper_instances_), though I haven't actually checked how plugins
currently behave in OOPIFs.

Acknowledged.

   RenderWidget::OnSetFocus(enable);
