Fix SubtreeLayoutScope not to schedule relayout

This patch fixes SubtreeLayoutScope::setNeedsLayout() and
setChildNeedsLayout() not to schedule relayout when they call
markContainerChainForLayout().

The signature of markContainerChainForLayout() allows to schedule
relayout even when SubtreeLayoutScope exists. To not allow scheduling
relayout while we're in layout, this patch changes the signature.
