Mark WindowOrWorkerGlobalScope.p.origin in Safari (#6634)
Mark WindowOrWorkerGlobalScope.p.origin in Safari (#6634)

This change marks WindowOrWorkerGlobalScope.p.origin as supported in
Safari 11 — per https://bugs.webkit.org/show_bug.cgi?id=168023, which
per https://trac.webkit.org/browser/webkit/tags/Safari-604.2.4/Source/WebCore/page/WindowOrWorkerGlobalScope.idl#L31
was first added in Safari 11, because per
https://trac.webkit.org/browser/webkit/tags/Safari-603.2.1/Source/WebCore/page/WindowOrWorkerGlobalScope.idl
it was not in the tag for Safari 10.1
