runtime: push down systemstack requirement for tracer where possible Currently lots of functions require systemstack because the trace buffer might get flushed, but that will already switch to the systemstack for the most critical bits (grabbing trace.lock). That means a lot of this code is non-preemptible when it doesn't need to be. We've seen this cause problems at scale, when dumping very large numbers of stacks at once, for example.
