LibWeb: Account for box-sizing:border-box in layout-less definite sizes

When we determine that a size is definite because it can be resolved now
without performing layout, we also need to account for the box-sizing
property.

This lets us remove a hack from flex layout where box-sizing:border-box
was manually undone at one point in the layout algorithm.
