[SVG] Implement `getPathData()` on `SVGPathElement`
Implements the `SVGPathData` interface mixin from the SVG Paths spec
[1] on `SVGPathElement`, exposing:
`sequence<SVGPathSegment> getPathData(optional SVGPathDataSettings);`
plus the `SVGPathSegment {type, values}` and `SVGPathDataSettings
{normalize}` dictionaries.
The method reads the `d` attribute base value (ignoring SMIL/CSS) and,
for <use> shadow instances, forwards to `CorrespondingElement()`.
With `{normalize: true}`, segments are reduced to absolute M, L, C,
Z via `SVGPathNormalizer`.
Gated behind the new experimental runtime flag `SVGPathDataAPI`.
Instrumented via `SVGPathElementGetPathData` and
`SVGPathElementGetPathDataNormalized` use counters.
