a6913835 - Remove the turbopack-build-events trace span, use `next build` instead (#96746)

Remove the turbopack-build-events trace span, use `next build` instead (#96746) * remove the synthetic turbopack-build-events parent, instead use `next build` as the parent * ensure that the trace uploader captures persistence and compaction This simplifies things a bit and may make reporting these traces more reliable, since they aren't reporting to a span with `0` duration
