cl-types: Improve error messages

* lisp/emacs-lisp/cl-extra.el (cl--derived-type-generalizers):
Check that the type is valid and fully defined.

* lisp/emacs-lisp/cl-lib.el (cl-generic-generalizers) <derived-type>:
Don't delegate to another method just because the type is invalid.

* lisp/emacs-lisp/cl-preloaded.el (cl--define-derived-type):
Minor simplification, and improvement to an error message.

(cherry picked from commit ceba490da921399393200e704520d313eb1ac5c8)
