Use SVGLength's wrapped CSSPrimitiveValue for pres.attr. style

Use SVGLength's wrapped CSSPrimitiveValue for pres.attr. style

Since SVGLength now wraps a CSSPrimitiveValue, there's no need to create
a (potentially new) CSSPrimitiveValue when collecting presentation
attribute style for SVG elements. Could save an allocation in some
cases.
Gets rid of the addSVGLengthPropertyToPresentationAttributeStyle helper
on SVGElement.
