Don't check for property tree nodes for ignored transform animations.

Transform properties are ignored on inline elements.  This code change
makes us stop expecting to have a property tree node for an animation
that is animating a transform property on an inline element.  This means
that we won't assert about the inconsistency of having some but not all
of the expected property tree nodes, which was introduced in
https://crrev.com/c/3307117 , when we stopped creating all such nodes
for any animation on the compositor.

We still don't animate such animations on the compositor, but this does
add a comment noting that we might be able to do so, and probably means
there's one less stumbling block in the way of doing so.

The added test hits a DCHECK() without the code change.
