Removes the policy-controlled "document-domain" feature. This feature was specified for the benefit of Permissions and Document Policy. If the feature was enabled, assigment to document.domain was aborted with a SecurityException.
The feature-controlled assignment to document.domain was implemented in Chromium browsers, but never default enabled. The originally intended goal of this feature is now being served by the Origin-Agent-Cluster http header.
