WIP This divorces SVGShadowRootElement from ShadowRoot. Now ShadowRoot owns the IsShadowRoot flag and shadowHost accessor and SVGShadowRootElement gets an isSVGShadowRoot virtual and svgShadowHost accessor. The divorce is moderately messy because a bunch of special cases for shadows are now two-way tests. Because there is often special-casing for SVG nearby, I wonder if a more aggressive clean-up will yield a cleaner result… Alternatively, we could try replacing SVGShadowRootElement with ShadowRoot. What makes that tricky is that ShadowRoot isn’t an SVGElement, which a lot of SVG-special casing is predicated on.
