Remove y_flipped from serialized CompositorFrames

We use serialized frames for perf testing, but as we are planning to
remove y_flipped field from TextureDrawQuad in a favor of using origin
on the TrasnferableResource, we need to update resources here.

Note, that these tests don't really have any resources, so flip doesn't
matter anyway.
