LibWeb: Make min-content height equivalent to max-content as appropriate

Browse source 
Per CSS-SIZING-3, the min-content block size should be equivalent to the
max-content block size for some boxes.

Honoring this gives more correct results, and avoids unnecessary work in
many cases since the cached max-content size can be reused.
