[improve][broker] PIP-429: Optimize Handling of Compacted Last Entry by Skipping Payload Buffer Parsing

[BewareMyPower]

PIP: #24439

Verifying this change

The functionality is covered by existing tests. testGetLastMessageIdForEncryptedMessage is added to verify that getLastMessageId still works when encryption is enabled. It does not work without introducing the compacted_batch_indexes field to MessageMetadata because the broker side does not know how to deserialize the SingleMessageMetadata.
