cherry-pick #14968 to release-3.0
What problem does this PR solve?
in #9127, we push constraint check down to tikv layer when prewrite phase.
but it miss the situation that txn add record a then delete record a, we also need check record is real duplicate when commit.
so just as
TestDeferConstraintCheckForDelete, it will lead to "delete wrong data"(primary key) or "inconsist index data"(unique key)What is changed and how it works?
we can do a addition batch get check for those key before commit just like pre-#9127 logic
but maybe better to follow #9127's idea just check it with prewrite mutation flag.
