    CIP: Pull out segment parsing to separate functions
    
    dissect_cip_segment_single was huge and too hard to read and update.
    This change pulls out segment parsing into individual functions to make
    it easier to read, and will help with upcoming changes.
    
    There are no functional changes. I verified that the packet parsing is
    identical before and after using feature_cip_all_segments.pcap from
    Bug: 12049
    
    Main changes:
    1. Pulled out the following code into separate functions:
       dissect_segment_port
       dissect_segment_safety
       dissect_segment_data_simple
       dissect_segment_ansi_extended_symbol
       dissect_segment_logical_service_id
       dissect_segment_logical_special
       dissect_segment_network
    2. In dissect_cip_segment_single, no need to explictly check for zero
       segment_len in many cases because the function will already return
       zero in those cases.
