KIP-1319 — Align TxnOffsetCommit API with OffsetCommit API

Accepted Kafka 4.4 ProtocolTransactionsConsumer

Introduces TxnOffsetCommit v6, which carries topic IDs instead of topic names, renames GenerationId to GenerationIdOrMemberEpoch, and enables GROUP_ID_NOT_FOUND, STALE_MEMBER_EPOCH and UNKNOWN_TOPIC_ID error codes. TxnOffsetCommit never received the KIP-848 enhancements applied to OffsetCommit, so it still hardcodes `Uuid.ZERO_UUID` in persisted OffsetCommitValue records and collapses both GROUP_ID_NOT_FOUND and STALE_MEMBER_EPOCH into ILLEGAL_GENERATION.
