    wifi: rtw89: add use of pkt_list offload to debug entry

    Driver can prepare pkt_list for firmware that only uses them to send out
    the packets in specific situations. To understand the usage of current
    status, and to check if there is leakage problem, dump bitmap and the
    indices used by certain function.

    An example looks like:

      map:
                    ...
            pkt_ofld:  3f 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ...
                    [SCAN 0]: 3
                    [SCAN 1]: 4
                    [SCAN 3]: 5
      VIF [0] xx:xx:xx:xx:xx:xx
                    ...
            pkt_ofld[GENERAL]: 0 1 2
