In normal-mode, make c-mode call c-mode when CC Mode is loaded

As regards which mode normal-mode calls for the symbols c-mode,
etc., the first of the following which applies holds:
(i) If the user has made a pertinent entry in
major-mode-remap-alist, this is used.
(ii) If CC Mode has been loaded, c-mode is called.
(iii) If library c-ts-mode has been loaded, c-ts-mode is
called.
(iv) Otherwise c-mode is called.

* lisp/progmodes/cc-mode.el (top level): Add entries to
major-mode-remap-defaults to implement the above.
