cc : Set 'needs update' on transform tree only when something changes

TransformTree::SetRootTransformsAndScales should set 'needs_update' on
transform tree only if we are changing the transforms stored on the root
or the contents_root node. Otherwise, we will end up updating transforms
every frame.
