[LayoutNG] Auto block-size shouldn't prevent child margin propagation.

The block-end margin strut of a child can collapse with the block-end
margin strut of the parent if the computed block-size of the child is
auto. This includes unresolvable percentages (e.g. if the child has a
percentage block-size, but its containing block has auto block-size).
