LibWeb: Make tiled backgrounds scroll with content
Previously the page background was always draw relative to the viewport instead of following with the content. This should eventually become an opt-in mode (via CSS "background-attachment") but for now let's have the default behavior be that backgrounds scroll with content. Also take this opportunity to move the background painting code from the two web views to a shared location in InitialContainingBlockBox.
