Remove initial size from WebContentsView::CreateView()

The size is not used intentionally because it can be wrong, but is
plumbed around by everyone anyways. The only consumer is for browser
plugin. Since the size is updated shortly after (that's why it is ok
to ignore says the comment in WebContentsViewAura) we don't need all
these setters and plumbings just for WebContentsViewGuest.
