add preset for highway=service mapped as areas (#463)

see https://wiki.openstreetmap.org/w/index.php?title=Tag:highway%3Dservice&oldid=2321782#Linear_ways_and_areas

preset is non-searchable as usage is pretty niche and showing the preset in search results could potentially mislead mappers to misuse the tag
