  [LBSE] Fix clipping + SVGUseElement support
https://bugs.webkit.org/show_bug.cgi?id=265244

Reviewed by Rob Buis.

Teach pathFromGraphicsElement() about SVGUseElement, and use that
to support <use> as <clipPath> children in LBSE. The legacy SVG
engine uses the deprecated virtual SVGUseElement::toClipPath()
function -- LBSE no longer makes use of these code paths.

Covered by existing tests - 5+ fixed tests in LBSE.
