Bug 2033191 made sure we only call ownerGlobal on nodes. As per the discussion in dev-platform, the front-end ~always wants .documentGlobal. This removes ownerGlobal from the bindings. Following patch will rename internal GetOwnerGlobal in gecko to GetRelevantGlobal as per the HTML spec terminology. Differential Revision: https://phabricator.services.mozilla.com/D297183
