LibWeb: Position absolute block-level boxes below previous siblings

Whether an absbox is positioned below or to the right of its previous sibling in an `InlineFormattingContext` is determined by the display-outside value before blockification, so we store the pre-blockification `display` value in `ComputedValues` to access it in `InlineFormattingContext` and position the box accordingly.
