Update handling of advices during preload

* lisp/emacs-lisp/comp-common.el
(native-comp-never-optimize-functions): Remove macroexpand and
rename-buffer from default value.
* lisp/emacs-lisp/comp.el (comp-call-optim-form-call): Document call
optimization for advised primitives.
* lisp/emacs-lisp/nadvice.el (advice-add): Remove references to TODOs
that were completed already earlier.
* lisp/loadup.el: Disallow advices during preload.  (Bug#67005)
