Commit: Arash Esbati <arash@gnu.org>

    Use font-lock face names instead of variables
    
    * tex-font.el (tex-font-lock-syntactic-face-function): Return face
    names and not the variables version which is obsolete with Emacs
    31 (commit 3d3c1094).
    (tex-math-face): Delete variable.  (bug#74939)
