[css-grid] Apply flow-aware logic for margins during stretching

[css-grid] Apply flow-aware logic for margins during stretching

We need to consider orthogonality when using the item's logical margin to
compute the available space for stretching.

The issue this CL fixes is only reproducible when the grid layout logic
is executed several times, since probably the item doesn't need to be
laid out again. In such cases, we just get the cached logical margins
but we were not taking orthogonality into account.
