Minor optimization of SVG <textPath> layout

Path::pointAtLength and Path::normalAngleAtLength both call
Path::pointAndNormalAtLength to do the work.
SVGTextLayoutEngine::layoutTextOnLineOrPath call the two former, which
means it'll setup and process the path twice.

Change the two calls into one call to pointAndNormalAtLength to reduce
the work required.
