SVG wastes time in stringToLengthType, should use CSS parser (or atoms) instead

SVG is wasting time in stringToLengthType (in DOM string creation and
destruction).  The HTML side of things just uses the CSS parser to extract
length type during length parsing.  SVGLength should either find a cheaper
method for parsing, or use the CSS parser code.

I discovered this by using the "heavy" view in shark, noting the malloc was
heavy, and then seeing that stringToLengthType was under the String::String()
malloc caller.
