    c++/reflection: add var tmpl to inform_tree_category [PR124493]

    Modifying the recently added crash22.C test to use a variable template
    shows that inform_tree_category doesn't say reflection of what we
    actually got.  With this patch we say:

      ⢠but 'Y<T>' is a variable template
        crash23.C:6:13:
            6 | constexpr T Y{};
              |             ^

    I couldn't figure out a test for alias templates so I'm not adding
    that now.

            PR c++/124493

    gcc/cp/ChangeLog:

            * error.cc (inform_tree_category): Handle variable templates.

    gcc/testsuite/ChangeLog:

            * g++.dg/reflect/crash23.C: New test.
