LibWeb: Support more length types in SVG width/height attributes

Browse source 
Previously we were using the HTML parse_dimension_value method for the
height and width attributes of an SVG element. These attributes should
however be treated as css properties instead and thus also support
calc() and absolute units so we use the css parser for this instead.
