cmd/trace: trace.Logf messages missing from timeline

[prattmic]

In the new execution tracer, cmd/trace is missing handling of trace.Logf messages and thus simply omits them from the timeline.

Can I work on this? @prattmic

Thanks for offering! I would normally say I'd love your help, but since this is a regression, it should probably be a release blocker for 1.22 (I forgot to mark that this morning) and thus fixed ASAP. Thus it is probably best for either myself or @mknyszek to take.
