    libstdc++: Define noop coroutine details private and inline [PR 95917]

    This moves the __noop_coro_frame type, the __noop_coro_fr global
    variable, and the __dummy_resume_destroy function from namespace scope,
    replacing them with private members of the specialization
    coroutine_handle<noop_coroutine_promise>.

    The function and variable are also declared inline, so that they
    generate no code unless used.

    libstdc++-v3/ChangeLog:

            PR libstdc++/95917
            * include/std/coroutine (__noop_coro_frame): Replace with
            noop_coroutine_handle::__frame.
            (__dummy_resume_destroy): Define inline in __frame.
            (__noop_coro_fr): Replace with noop_coroutine_handle::_S_fr
            and define as inline.
            * testsuite/18_support/coroutines/95917.cc: New test.=
