  [motion-path] Check if we are mid layout when setting containing block rect for ray

Reviewed by Simon Fraser.

On the first RenderLayer::updateTransform call the parent is mid layout, so it is
inorrect to query it about its rect size. If we have a motion path transform, set
that this RenderObject needs a transform update on the parent through the FrameView's
layout context, and have the parent call updateTransform after it has completed layout.
