    c++: Fix exported using decls of templates

    We need to look at DECL_TEMPLATE_RESULT to get the module attachment.

            PR c++/106849

    gcc/cp/ChangeLog:

            * name-lookup.cc (do_nonmember_using_decl): Handle
            TEMPLATE_DECLs when checking module attachment.

    gcc/testsuite/ChangeLog:

            * g++.dg/modules/using-9.C: New test.
