[improve][broker] Don't rollover empty ledgers based on inactivity (#21893)

### Motivation

When `managedLedgerInactiveLedgerRolloverTimeSeconds` is set, let's say to `300` (5 minutes), the ledger will also get rolled in the case when no new entries (messages) were added to the ledger. This doesn't make sense.
Empty ledgers are deleted, but having this extra churn is causing extra load on brokers, bookies, and metadata stores (zookeeper).

### Modifications

Skip rolling the ledger if it is empty.
