LibWeb: Support more kinds of indefinite widths on flex column items
This stuff is pretty hairy since the specifications don't give any guidance on which widths to use when calculating the intrinsic height of flex items in a column layout. However, our old behavior of "treat anything indefinite as fit-content" was definitely not good enough, so this patch improves the situation by considering values like `min-content`, `max-content` and `fit-content` separately from `auto`, and making the whole flex layout pipeline aware of them (in the cross axis context).
