wenquan1 95f8c54836 arch/sim: support SO_TIMESTAMPING TX in sim netdriver 
Add TX timestamp loopback support to the simulator network driver.
When a packet tagged with io_conn (SO_TIMESTAMPING TX) is sent,
the driver clones the packet, generates a software timestamp, and
queues it for loopback through the RX path. The protocol layer
(UDP/PKT) then delivers the timestamp via MSG_ERRQUEUE.

- Add tstampq IOB queue to sim_netdev_s for loopback packets.
- In netdriver_send(), clone timestamped packets with realtime
  clock and notify RX ready.
- In netdriver_recv(), return loopback packets before reading
  from the tap device.
