[css-layout-api] Don't use LayoutNG for custom layout children. 

Custom layout children may not establish new formatting contexts, and
since the custom container itself is laid out by the legacy engine, we
need to force its children to be laid out by legacy as well.

Added a margin collapsing test that used to fail in NG because of this.
