Revert of binding: Removes Document::wrap that must be equivalent to Node::wrap. (patchset #5 id:100001 of https://codereview.chromium.org/2525313004/ )

Reason for revert:
CHECK(!frame->document()->containsWrapper()); in WindowProxy::updateDocumentProperty() is causing crashes at several places.

Original issue's description:
> binding: Removes Document::wrap that must be equivalent to Node::wrap.
>
> Removes unnecessary Document::wrap and associateWithWrapper.
> The special code in these functions were made in order to keep
> WindowProxy::m_document updated and consistent with toV8(document).
> But we no longer rely on the hack, and we can remove the dead code.
