    libstdc++: Simplify and comment std::jthread extension [PR100612]

    Use a requires-clause on the partial specialization of the
    __pmf_expects_stop_token variable template, which is used for the
    extension that allows constructing std::jthread with a
    pointer-to-member-function that accepts a std::stop_token argument.

    Also add a comment referring to the related Bugzilla PR.
