[LayoutNG] Multi-column containing blocks

Currently, when a multi-column is a containing block for an OOF
positioned element, the corresponding column is mistaken for the
containing block, which causes various DCHECK failures. Columns are not
allowed to be containing blocks, so this change ensures that we skip
over columns when placing OOF positioned elements.
