Automatic update from web-platform-tests[css-layout-api] Populate children, and pass into layout() function
This introduces the LayoutChild API surface, (which only has a styleMap
accessor currently).
Each LayoutBox which is a child of a LayoutCustom will hold onto a
LayoutChild object, acting as the script interface for the web
developer.
