Require ert-x for use by 'ert-font-lock-deftest-file'

This fixes a void-function error when 'ert-font-lock-deftest-file'
is called when ert-x has not already been loaded.
* lisp/emacs-lisp/ert-font-lock.el (ert): Require ert-x so that
'ert-resource-file' is available for use within
'ert-font-lock-deftest-file'.  (Bug#73254)
