This reverts commit 985a1f41.

Reason for revert: https://crbug.com/1055738

Original change's description:
> Don't disable draw during resize
> 
> https://crrev.com/c/2011130 changed Display::DisableSwapUntilResize() to
> also block draw instead of just swap. This had the side of effect of
> blocking draw when the browser window is minimized, which means we stop
> casting tab/window contents. Switch DisableSwapUntilResize() back to
> just block swap instead of draw+swap.
