    libstdc++: Ensure all feature test macros have type long [PR87193]

    This defines all the __cpp_lib_xxx macros as type long, as required by
    the standard. We had an inconsistent mix of int and long, sometimes even
    for the same macro name.

    The __cpp_lib_experimental_xxx macros are left as type int, because
    that's what it says in the relevant TS specs.
