Make SVGLength store a const CSSValue

Make SVGLength store a const CSSValue

Make SVGLength::m_value a Member<const CSSPrimitiveValue> instead of
non-const. This also involved making
Element::addPropertyToPresentationAttributeStyle take a const ptr, and
MutableStylePropertySet::setProperty() take a const ptr.

This is an entirely mechanical change that is more semantically correct
and safe, and is pre-work for making CSSPropertyParser::parseSingleValue
return a const CSSValue*.
