Yanqin Jin bd513fd075 Add commit marker with timestamp (#9266) ... Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/9266 This diff adds a new tag `CommitWithTimestamp`. Currently, there is no API to trigger writing this tag to WAL, thus it is unavailable to users. This is an ongoing effort to add user-defined timestamp support to write-committed transactions. This diff also indicates all column families that may potentially participate in the same transaction must either disable timestamp or have the same timestamp format, since `CommitWithTimestamp` tag is followed by a single byte-array denoting the commit timestamp of the transaction. We will enforce this checking in a future diff. We keep this diff small.
