[LayoutNG] Multicol writeback to legacy layout
In the case of external/wpt/css/css-multicol/multicol-span-all-016.html,
one column set is created before the spanner, but no column set is
created after the spanner. In NG, columns with content may be created
after the spanner, resulting in incorrect bounds when querying
legacy layout. To fix this, extend the last column set when building up
the flow thread in NGBlockNode::PlaceChildrenInFlowThread() to
encompass any content after the spanner.Bug: 1210287
