gfe-relnote: In BandwidthSampler, capture the number of lost bytes at the time a packet is sent, and make it available to caller when the packet is acked or lost. No behavior change, not protected.

In addition to the number of lost bytes, this CL also makes the number of sent bytes and number of acked bytes available to caller when a packet is acked or lost.

This is needed for BBRv2 to set inflight_hi when loss is high.
