[SVG] Implement `setPathData()` on `SVGPathElement`
Implements `setPathData(sequence<SVGPathSegment> pathData)` from the
SVG Paths spec [1] on `SVGPathElement`.
Valid segments are built into an SVGPathByteStream (via
SVGPathByteStreamBuilder), then applied through `setAttribute("d", …)`
so the existing mutation pipeline (invalidation, <use> instances,
MutationObservers) fires. A leading non-moveto yields an empty path;
on the first invalid segment (unknown type, wrong arity, non-finite
value, non-binary arc flag) that segment and all after it are dropped.
Gated behind the existing experimental runtime flag `SVGPathDataAPI`.
Instrumented via the `SVGPathElementSetPathData` use counter.
