layout: Layout for column flex-basis and minimum automatic size determination (#33068)

Browse source 
This change adds an expensive layout for the determination of minimum
automatic size and flex basis in process of flexbox layout. Currently,
the layout is not cached, so may be performed up to 2 more times than
necessary.
