What problem does this PR solve?

To avoid committing a transaction with MAX_UINT64 unexpectedly.
Sometimes (PointGet, Analyze) TiDB uses special startTS (MAX_UINT64) to initialize a transaction. This is dangerous because txn.Commit() may be called unexpectedly.

What is changed and how it works?

cherry-pick #9555
