    Adjust the deduction guides for std::function and std::packaged_task to
    work with static call operators. This finishes the implementation of
    P1169R4 for C++23.

            template.
            [__cpp_static_call_operator] (__function_guide_static_helper):
            New class template.
            (function): Use __function_guide_t in deduction guide.
            * include/std/future (packaged_task): Use __function_guide_t in
            deduction guide.
            * testsuite/20_util/function/cons/deduction_c++23.cc: New test.
