Remove a no-op + not overriden WebContentsDelegate::WebUISend method.

The content::WebContentsDelegate::WebUISend virtual method is a no-op
and is not overriden anywhere.  Therefore it should be safe to just
delete this method and stop calling it (since calling it is a no-op).

The only caller of content::WebContentsDelegate::WebUISend was
WebContentsImpl::OnWebUISend method which is also deleted by this CL.

ViewHostMsg_WebUISend is *not* being deleted - it is still handled by
the browser in content::WebUIImpl::OnWebUISend.
