    libstdc++: Rename __cpp_lib_constexpr_invoke macro
    
    This macro was renamed after it was added to the working draft, but we
    never renamed it  in libstdc++. We haven't made a release with the old
    macro name, so I see no need to keep it around.
    
            * include/std/functional (__cpp_lib_constexpr_invoke): Rename to
            __cpp_lib_constexpr_functional.
            * include/std/version (__cpp_lib_constexpr_invoke): Likewise.
            * testsuite/20_util/function_objects/invoke/constexpr.cc: Adjust.
