TestIndexWriterMergePolicy.testStressUpdateSameDocumentWithMergeOnCommit fails on nightly

### Description

This fails with an OOM on nightly. I wonder if we are just merging too much :).

I suspect this is due to the tiered merge policy change, but I might be wrong. haven't ran gitbisect.

```

### Gradle command to reproduce

```
./gradlew test --tests TestIndexWriterMergePolicy.testStressUpdateSameDocumentWithMergeOnCommit -Dtests.seed=C13C284249671712 -Dtests.nightly=true -Dtests.locale=rwk-TZ -Dtests.timezone=Antarctica/Macquarie -Dtests.asserts=true -Dtests.file.encoding=UTF-8
```

Run the supplied Gradle command with the listed seed and nightly settings, then read TestIndexWriterMergePolicy.java around testStressUpdateSameDocumentWithMergeOnCommit and stressUpdateSameDocumentWithMergeOnX. Trace the reported merge, flush, and FieldUpdatesBuffer frames to identify the cause; done means the nightly test completes without the OOM or follow-on failures.
