LibWeb: Generalize support for dimension attributes

Browse source 
Rather than each element which supports dimension attributes needing to
implement parsing the attributes and setting the appropriate style, we
can generalize this functionality. This will also make each element more
closely resemble the spec text, as we will be effectively declaring, for
example, "The img element supports dimension attributes" in code.
