    libstdc++: Restore __gnu_debug::array [PR100682]

    As the PR points out, we removed the debug version of std::array without
    any period of deprecation. Although std::array contains all the actual
    debug checks now, removing the <debug/arrray> header breaks any code
    that was using that explicitly. The manual still lists doing that as
    supported.

    This restores the <debug/array> header, but simply defines
    __gnu_debug::array as an alias for std::array, and declares the alias
    with the deprecated attribute. The docs are updated to match.
