(built-in-class--make): Take list of types rather than classes

Consolidate the conversion from types to classes into
`built-in-class--make` instead of duplicating it in ever caller.

* lisp/emacs-lisp/cl-preloaded.el (built-in-class--make): Take list of
types rather than classes.
(cl--define-built-in-type): Simplify accordingly.
