    Improve ACL comparison efficiency

    The current comparison strategy is very time-consuming, and if
    there are hundreds of thousands of security group rules, the
    comparison time can still vary from several hours. The main
    time-consuming operations are [1].

    This patch is sorted first by security group rule ID and then
    compared. The execution of sorting actions is relatively fast.
    After actual measurement, the total time consumption is in the
    minute level.
