    libstdc++: Improve Doxygen docs for std::allocator_traits specializations
    
    The main fix here is to use @header so that the docs show the correct
    header file instead of an internal header like alloc_traits.h.
    
    libstdc++-v3/ChangeLog:
    
            * include/bits/alloc_traits.h: Improve doxygen docs for
            allocator_traits specializations.
            * include/bits/memory_resource.h: Likewise.
