move Autoconf indices to a submenu

[Paul Eggert]

The current autoconf top-level menu has more than two dozen entries,
which is a bit much.  How about moving the indices to a submenu?  This
shouldn't break 'info', as it looks sequentially for the first section
name containing the word 'Index'.

        * doc/autoconf.texi: Move indices out of the top level menu
        and into a submenu.
