    libstdc++: Make std::function deduction guide support explicit object
functions [PR113335]

    This makes the deduction guides for std::function and std::packaged_task
    work for explicit object member functions, i.e. "deducing this", as per
    LWG 3617.

    libstdc++-v3/ChangeLog:

            PR libstdc++/113335
            * include/bits/std_function.h (__function_guide_helper): Add
            partial specialization for explicit object member functions, as
            per LWG 3617.
            * testsuite/20_util/function/cons/deduction_c++23.cc: Check
            explicit object member functions.
            * testsuite/30_threads/packaged_task/cons/deduction_c++23.cc:
            Likewise.=
