[atkmm] Allow other modules to use the m4 files.

[Murray Cumming <murrayc src gnome org>]

commit 1d154b3916b9c3b401575533230478014c985fd1
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Jan 7 23:31:56 2011 +0100

    Allow other modules to use the m4 files.
    
    * codegen/Makefile.am: Install the m4 files, like gtkmm installs its files.
    * atk/atkmm.pc.in: Add the gmmproc4mdir variable so that other modules such
    as gtkmm and cluttermm can get the path to the m4 file, to avoid
    duplicating its contents.
