URL: https://github.com/apache/pulsar/pull/15282
### Motivation

as below:
- When `individualDeletedMessages` exceeds `maxUnackedRangesToPersist`.
- When the cursor is closing, there may be other acks that are executing
asynchronously, causing the cursor to persist not the latest
`individualDeletedMessages`.
We can add `individualDeletedMessagesSize` to the log to help pinpoint the
problem.
