Rows are lost for 100K table and go-ycsb workload test

[Tammyxia]

What did you do?

• BR restore 100K source data to upstream and downstream TiDB cluster.
• Create a changefeed, then run workload: go-ycsb load and run on table prefix unit2_.
• Run test case with chaos: upstream all node restart, cdc owner switch, all upstream unavailable, PD leader switch.
• Check data correctness between upstream and downstream TiDB cluster.

Reproduce again in this test.

It should be fixed by tikv/tikv#12262 let's keep it open and wait for another round of testing.
