Minor shortdoc link improvements

* lisp/emacs-lisp/shortdoc.el (shortdoc--display-function): Use
describe-function as a fallback link when a function is not documented
in any Info manual.  Also make the link respond to mouse-1, like the
rest of *Help* links, and add a proper help-echo property.
* lisp/help-fns.el (help-fns--mention-shortdoc-groups): Same link
improvement as described before, this time for the shortdoc groups
(bug#45750).
