Subject: [PATCH] Mark function obsolete & fix spelling of its name

* lisp/org-macs.el (org-truely-invisible-p): Move to...
* lisp/org-compat.el (org-truly-invisible-p): ...here, and add...
  (org-truely-invisible-p): ...this compatibility alias.

There are no callers of this function in Org Mode, nor in current
Emacs (on the 'master and 'emacs-28' branches at least).  We discussed
whether to remove it entirely, and for now seem to have tentatively
decided not to remove it.  See this thread for more details:
