What problem does this PR solve?

@@tidb_disable_txn_auto_retryis set to0, transactions will retry automatically when there are write conflicts, but when there are select for update statements, auto-retry should be prevented. A previous PR #10972 makespoint getplan supportsselect for update, but didn't setTransactionContext.ForUpdateto true, so the transaction will retry even it hasselect for updatestatements.What is changed and how it works?
extract a function
doLockKeysthat used by bothSelectLockexecutor andPointGetexecutor. In this function, setTransactionContext.ForUpdateto true.Check List
