Fix 3d transform check in HasDistortingVisualEffects

https://crrev.com/1629048 relies on HasDistortingVisualEffects
catching all cases where the target has a 3d transform. Unfortunately,
this was not the case because
GeometryMapper::SourceToDestinationProjection will flatten 3d
transforms, so the following check is insufficient:

  gfx::Transform projection = SourceToDestinationProjection(
      paint_properties.Transform(), root_properties.Transform());
  if (!projection.Is2dProportionalUpscaleAndOr2dTranslation())
    return true;

This patch fixes this issue by ensuring that the target and the root
are coplanar before relying on the projection.
