LibWeb: Determine intrinsic flex container size from content-size

Browse source 
When running the min-content and max-content sizing algorithms and the
target box creates a flex formatting context, we don't need to measure
its children.

FFC has already assigned the content_width and content_height values,
so we just need to pick those up from the container's formatting state.
