  [IFC][Integration] Enable nested out-of-flow boxes for IFC

Reviewed by Antti Koivisto.

LineLayout::containing should treat out-of-flow boxes as if they were statically positioned.

Out-of-flow boxes participate in IFCs as if they were in-flow content. When trying to find the associated LineLayout object, we need to apply the same logic
(i.e. find the containing block as if they were in-flow).
