Autoload some string functions

These functions are documented in both `(elisp) Creating Strings' and
'M-x shortdoc RET string RET', so users will expect them to be available
without having to require 'subr-x'.

* lisp/emacs-lisp/subr-x.el (string-fill, string-limit, string-pad)
(string-chop-newline): Autoload.
