    libstdc++: Change comment on #endif to match #if condition [PR124363]
    
    I changed the #if in r8-3123-gc6888c62577671 but didn't make the
    corresponding change to the #endif.
    
    This backport also includes the fix for the #endif of the include guard,
    which was changed by r16-6038-g62c126db6b6017 to refer to the correct
    macro.

            * include/std/string_view: Adjust comment on #endif to match #if
            condition. Likewise for header guard.
    
    (cherry picked from commit 47339c8f8a477464b6fe44992200bd2b840da8f4)
