    c++: Fix class NTTP constness handling [PR98810]

    Here, when substituting still-dependent args into an alias template, we see
    a non-const type because the default argument is non-const, and is not a
    template parm object because it's still dependent.

    gcc/cp/ChangeLog:

            PR c++/98810
            * pt.c (tsubst_copy) [VIEW_CONVERT_EXPR]: Add const
            to a class non-type template argument that needs it.

    gcc/testsuite/ChangeLog:

            PR c++/98810
            * g++.dg/cpp2a/nontype-class-defarg1.C: New test.
