Avoid scheduling rendering updates for SVG animations on elements
without renderers
https://bugs.webkit.org/show_bug.cgi?id=298217
rdar://159647563
Reviewed by Antoine Quint.
When SVG elements with SMIL animations (like animateTransform) are
inside containers with hidden attribute, the legacy SVG engine was
scheduling full page rendering updates every animation frame despite
the elements having no renderer.
Now when animations run on elements without renderers, we skip
scheduling rendering updates entirely.
