PR-20833: [improve][broker] Add bookkeeperDeleted in topic internal stats.

[streamnativebot]

url: apache#20833

Motivation

Shows the offload detail of the ledgers whether it is deleted in bookkeeper.

The ./bin/pulsar-admin topics stats-internal command now shows the ledger info of specific topic. If we are using offloader, we can know the offloaded of the ledger but not be able to know whether it is deleted in bookkeeper.

Modifications

Add bookkeeperDeleted field in org.apache.pulsar.common.policies.data.ManagedLedgerInternalStats.LedgerInfo. Fill the bookkeeperDeleted in all places where offloaded be filled.
