What problem does this PR solve?

Issue Number: close #23909

Problem Summary:

The REPLACE statements requires Insert+Delete privileges, and INSERT INTO ON DUPLICATE requires Insert+Update privileges, but currently TiDB only checks for the Insert privilege, allowing users to delete or change records even without the permission.

What is changed and how it works?

Add back the extra privilege check when the InsertStmt contains the OnDuplicate clause or IsReplace.
