In 253606 at main I made it possible for the primary layer of a GraphicsLayer to be a CATransformLayer.
However, we had existing code that unconditionally cause -contentsScale and -rasterizationScale to
be set on all CALayers, and these don't make sense on a CATransformLayer, which never has painted
content.

So conditionalize calling `noteLayerPropertyChanged(ContentsScaleChanged)` to only happen on
non-transform layers.
