LibWeb: Sketch out a very basic SVG <clipPath> element

This element doesn't actually support anything at the moment, but it
still massively speeds up painting performance on Wikipedia! :^)

How? Because we no longer paint SVG <path> elements found inside
<clipPath> elements. SVGClipPathElement::create_layout_node() returns
nullptr which stops the layout tree builder from recursing further into
the subtree, and so the <path> element never gets a layout or paint box.

Mousing over Wikipedia now barely break 50% CPU usage on my machine :^)
