  Log Message:
  -----------
  [clangd] Trace queue state for each TUScheduler action.

The new trace event includes what's already in the queue when adding.
For tracers that follow contexts, the trace event will span the time that the action
spends in the queue.
For tracers that follow threads, the trace will be a tiny span on the enqueuing thread.
