WebGUI::Session::Http should go away (#11647)

Move logic out of WebGUI::Session::HTTP and into WebGUI::Session::Response /
::Request; deprecate more functions; change references in core to use
$session->response instead; fix tests that broke because of the change but
not one that merely generate the deprecated warning because I want to know
that the proxying of depricated methods is working.  These can be changed later.
