Missing timing information for TCP accesslog

*Title*: *As titled*

*Description*:
We have these fields defined in the accesslog common properties.

- `time_to_last_rx_byte`
- `time_to_first_upstream_tx_byte`
- `time_to_last_upstream_tx_byte`
- `time_to_first_upstream_rx_byte`
- `time_to_last_upstream_rx_byte`
- `time_to_first_downstream_tx_byte`

However using a configuration with listener level grpc accesslog, along with tcp proxy, and then setup the gRPC accesslog server in go, I see `nil` for all these attributes.

This will be useful for envoyproxy used a TCP proxy and debugging lots of connection termination details.

```
fmt.Printf("the connection: common.GetTimeToLastRxByte() %v, common.GetTimeToFirstDownstreamTxByte() %v,\n"+
"common.GetTimeToLastDownstreamTxByte() %v, common.GetTimeToFirstUpstreamRxByte() %v\n,"+
"common.GetTimeToLastUpstreamRxByte() %v, common.GetTimeToFirstUpstreamTxByte() %v, common.GetTimeToLastUpstreamTxByte() %v\n",
common.GetTimeToLastRxByte(), common.GetTimeToFirstDownstreamTxByte(),
common.GetTimeToLastDownstreamTxByte(), common.GetTimeToFirstUpstreamRxByte(), common.GetTimeToLastUpstreamRxByte(),
common.GetTimeToFirstUpstreamTxByte(), common.GetTimeToLastUpstreamTxByte(),
)
```

Checking code, looks like function `onUpstreamTxByteSent` is only invoked on router/generic proxy router filter, rather than tcp proxy filter. probably adding such invocation in the tcp_proxy filter's `onUpstreamData/onData` can be added to fill in these information.
