feat(3p/lisp/mime4cl): search for first (default) mime text part r/2853

Adds a simple generic function find-mime-text-part which returns the
first suitable text/* part in any MIME part it is given.

Has no meaningful alternatives handling at the moment: It will pick the
first text part and doesn't allow specifying a preference.
