[Layout] Avoid double relayout on window resize

While investigating youtube button, I've noticed that
window resize was always causing double relayouts.

What happens is that on window resize we do one layout,
notice size has changed, and always force another layout.

I think SetNeedsLayout call is not needed, as
MarkViewportConstrainedObjectsForLayout will already
mark ancestors for layout if needed.
