    c++: Fix deprecated attribute handling on templates (PR c++/93228)

    As the following testcase shows, when deprecated attribute is on a
template,
    we'd never print the message if any, because the attribute is not
    present on the TEMPLATE_DECL with which warn_deprecated_use is called,
    but on its DECL_TEMPLATE_RESULT or its type.

        in DECL_TEMPLATE_RESULT or its type's attributes.
