When changing children, we don't need to sync a layer state. We were confused that we have to send a parent layer id to UI Process, but r133605 clarified passing the parent id is not necessary. So this patch removes didChangeLayerState() in methods which change children. In addition, purgeBackingStores() does not need to call didChangeChildren() because purgeBackingStores() does not change children. r133605 is Bug 101142.

I wouldn't say we were confused, in the past behavior of GraphicsLayer we did have to send the parent. I would reword this to say "There is no more need to send the parent ID every time the layer tree hierarchy changes."
