trace_processor: support tcp_retransmit_skb event

The tcp_retransmit_skb ftrace event could be used to track packet timeout
or fast retransmit. The patch parse the tcp_retransmit_skb event and show
the event as instant on async task tracker.

Bug: 215086208

Test: ui/run-dev-server & manaul check the UI behavior

Test: tools/diff_test_trace_processor.py <trace_processor_shell> \
      --query-metric-filter='tcp_retransmit_skb'
