Reviewed by Nikolas Zimmermann.

On a transform change from identity matrix to non-identity matrix
the render layer needs to become a stacking context without relying on
a style update in the case of LBSE. Add logic for this in repaintOrRelayoutAfterSVGTransformChange.

Also add a correction to only call updateLayerTransform once in
repaintOrRelayoutAfterSVGTransformChange.
