[PR] [FLINK-37313] Fix the problem of reading binlog before the high and low watermarks during the snapshot process [flink-cdc]

gongzexin opened a new pull request, #3920:
URL: https://github.com/apache/flink-cdc/pull/3920

   This closes [FLINK-37313](https://issues.apache.org/jira/browse/FLINK-37313).
   
   # SnapshotSplitReader#isBackfillRequired
   If the binlog has not changed during the snapshot split read, the binlog should not be read.
   
   # MySqlStreamingChangeEventSource#handleChange
   Even if you read the binlog of a table you don't care about, you should update the timestamp to avoid MySqlBinlogSplitReadTask#handleEvent reading a large amount of binlog
