Move the m_didTransformToRootUpdate flag to LayoutSVGContainer

By pushing the update of the m_didTransformToRootUpdate flag out of the
various calculateLocalTransform() implementations, we both get
implementations of those methods that are more to the point, and expose
the redundant calls to SVGLayoutSupport::transformToRootChanged().
This also means that didTransformToRootUpdate() is devirtualized,
although it was never called "virtually" before either.
Also turn m_needsBoundariesUpdate into a single-bit flag.
