Merge bitcoin/bitcoin#23907: tracing: utxocache tracepoints follow up for #22902
799968e8b38833dc7fd7b6d488a66a14580ef674 tracing: misc follow-ups to 22902 (0xb10c)
36a65847033540cf2203252c7baf42bc5ec97579 tracing: correctly scope utxocache:flush tracepoint (Arnab Sen)
Pull request description:
This PR is a follow-up to the [#22902](https://github.com/bitcoin/bitcoin/pull/22902).
Previously, the tracepoint `utxocache:flush` was called, even when it was not flushing. So, the tracepoint is now scoped to write only when coins cache to disk.
