LibWeb: Adjust flex item main size through aspect ratio if needed

Browse source 
If there are min or max size constraints in the cross axis for a flex
item that has a desired aspect ratio, we may need to adjust the main
size *after* applying the cross size constraints.

All the steps to achieving this aren't mentioned in the spec, but it
seems that all other browsers behave this way, so we should too.
