This patch introduces version 6 of the TxnOffsetCommit API: * Adds a new `TopicId` field at `6+` and bounds the existing `Name` field to `0-5` on both the request and the response. * Renames the `GenerationId` field to `GenerationIdOrMemberEpoch` on the request to reflect its dual semantics under the new consumer group protocol (source-only rename; the wire format is positional and unchanged). * Ensures that the client cannot use version 6 yet. * Keeps the new version as unstable.
