Bug 1383650 - Add conversion utilities to get CSS counterpart of SVG unit and AttrEnum r=longsonr We need some utilities to convert SVG unit and attrenum to CSS unit and property id. This is useful when we need to pass parsed geometry property directly to CSS. Differential Revision: https://phabricator.services.mozilla.com/D30777
