    libstdc++: Document correct feature test macro, __cpp_lib_is_invocable
    
    The std::is_callable trait was renamed to is_invocable, but I never
    updated the manual to reflect the updated feature test macro.
    
            * doc/xml/manual/status_cxx2017.xml: Fix name of feature test macro.
            * doc/html/*: Regenerate.
