Add offload packets statistics

Add argument '--offload-stats' for command ovs-appctl bridge/dump-flows
to display the offloaded packets statistics.

The commands display as below:

orignal command:

ovs-appctl bridge/dump-flows br0

duration=574s, n_packets=1152, n_bytes=110768, priority=0,actions=NORMAL
table_id=254, duration=574s, n_packets=0, n_bytes=0, priority=2,recirc_id=0,actions=drop
table_id=254, duration=574s, n_packets=0, n_bytes=0, priority=0,reg0=0x1,actions=controller(reason=)
table_id=254, duration=574s, n_packets=0, n_bytes=0, priority=0,reg0=0x2,actions=drop
table_id=254, duration=574s, n_packets=0, n_bytes=0, priority=0,reg0=0x3,actions=drop

new command with argument '--offload-stats'

Notice: 'n_offload_packets' are a subset of n_packets and 'n_offload_bytes' are
a subset of n_bytes.

ovs-appctl bridge/dump-flows --offload-stats br0

duration=582s, n_packets=1152, n_bytes=110768, n_offload_packets=1107, n_offload_bytes=107992, priority=0,actions=NORMAL
table_id=254, duration=582s, n_packets=0, n_bytes=0, n_offload_packets=0, n_offload_bytes=0, priority=2,recirc_id=0,actions=drop
table_id=254, duration=582s, n_packets=0, n_bytes=0, n_offload_packets=0, n_offload_bytes=0, priority=0,reg0=0x1,actions=controller(reason=)
table_id=254, duration=582s, n_packets=0, n_bytes=0, n_offload_packets=0, n_offload_bytes=0, priority=0,reg0=0x2,actions=drop
table_id=254, duration=582s, n_packets=0, n_bytes=0, n_offload_packets=0, n_offload_bytes=0, priority=0,reg0=0x3,actions=drop

      * Add support for conntrack zone-based timeout policy.
    - 'ovs-dpctl dump-flows' is no longer suitable for dumping offloaded flows.
      'ovs-appctl dpctl/dump-flows' should be used instead.
+   - Add new argument '--offload-stats' for command
+     'ovs-appctl bridge/dump-flows',
+     so it can display offloaded packets statistics.
    - Add L2 GRE tunnel over IPv6 support.
