wgengine/netlog: embed node information in network flow logs (#17668)
This rewrites the netlog package to support embedding node information in network flow logs.
Some bit of complexity comes in trying to pre-compute the expected size of the log message
after JSON serialization to ensure that we can respect maximum body limits in log uploading.

We also fix a bug in tstun, where we were recording the IP address after SNAT,
which was resulting in non-sensible connection flows being logged.
