Anton 76abab9e20 feat: log bandwidth on substream instead of socket level (#3180)
Previously, the `with_bandwidth_logging` extension to `Transport` would track the bytes sent and received on a socket level. This however only works in conjunction with `Transport` upgrades where a separate multiplexer is negotiated on top of a regular stream.

With QUIC and WebRTC landing, this no longer works as those `Transport`s bring their own multiplexing stack. To still allow for tracking of bandwidth, we refactor the `with_bandwidth_logging` extension to count the bytes send on all substreams opened through a `StreamMuxer`. This works, regardless of the underlying transport technology. It does omit certain layers. However, there isn't necessarily a "correct" layer to count bandwidth on because you can always go down another layer (IP, Ethernet, etc).

Closes #3157.
