container: Request layout again depending on layout mode

Browse Source 
Containers with RESIZE_MODE_PARENT should never request layout and those
with RESIZE_MODE_IMMEDIATE should only request it for updating CSS.

Fixes clutter embeds (like the tray icon embed in gnome-shell)
continuously requesting relayout when all they want to do is relegate
relayout to Clutter.
