  An SVG element with a CSS reference filter fails to repaint when the filter changes

Reviewed by Nikolas Zimmermann.

If an SVG element has a CSS filter which references an SVG element (which may be a child of that SVG,
or some other SVG in the document), then we fail to repaint the SVG when the filter changes.

This is a followup to 267236 at main, removing the `&& !renderer().isSVGRootOrLegacySVGRoot()` check in
`RenderLayer::updateFiltersAfterStyleChange()`, since in this configuration we do need to have
the RenderLayer track the filter dependencies.
