This CL clones content::DocumentState / WebDocumentLoader::ExtraData and passes it to document loaders of empty documents replacing the current document as part of a discard operation or JavaScript URL navigation. DocumentState is cloned instead of extracted as the original document state object may be needed to process operations in the replaced document's unload handlers (such as same-site navigations, see linked bug). DocumentState::navigation_state_ is not cloned as this is specific to the document being replaced and should not be moved to the new empty document instance.
