I could see an argument for a specific before-save-hook for
org-edit-special. But currently, a solution can already be found for
your problem using the before-save-hook:
#+begin_src elisp
(defun my-maybe-call-macrostep-collapse-all ()
(when (and (org-src-edit-buffer-p)
(string-match-p (regexp-quote "emacs-lisp")
(buffer-name)))
(macrostep-collapse-all)))
(add-hook 'before-save-hook #'my-maybe-call-macrostep-collapse-all)
#+end_src
