Use SVGPathParser logic to traverse states of a Path
https://bugs.webkit.org/show_bug.cgi?id=44009
Move the getPathSegAtLength logic from SVGPathSegList into a new SVGPathConsumer
class: SVGPathTraversalStateBuilder.
This allows us to get a SVGPathSeg at a given length for SVGPathByteStreams and SVGPathSegLists.
It is also possible to use unaltered SVG path data, instead of just normalized path data.
This is the final preparation to provide normalized and unaltered SVGPathSegLists
on SVGPathElement.
