<!-- Please specify the module before the PR name: [core] ... or [flink] ... --> ### Purpose Currently, there are still many paimon users who need to support computed columns when synchronizing multiple tables in the entire database. This PR will implement this feature. If the referenced columned column exists in the table, the columned column function will be triggered. For example, ``` Table A column: col1 col2 col3 create_sys_tm Table B column: col1 col4 col4 create_sys_tm Define the calculated function: --computed_column="_substring=substring(col3,2), pt=date_format(create_sys_tm,yyyyMMdd)" The final table structure is as follows: Table A column: col1 col2 col3 _substring pt Table B column: col1 col4 col4 pt ``` The main changes of PR: Move the implementation of xxxRecordParser#evalComputedColumns down to RichCdcMultiplexRecordEventParser#evalComputedColumns ### Tests MySqlSyncDatabaseTableListITCase#testComputedColumn MongoDBSyncDatabaseActionITCase#testComputedColumn KafkaOggSyncDatabaseActionITCase#testComputedColumn KafkaMaxwellSyncDatabaseActionITCase#testComputedColumn KafkaCanalSyncDatabaseActionITCase#testComputedColumn ### API and Format <!-- Does this change affect API or storage format --> ### Documentation <!-- Does this change introduce a new feature --> -- This is an automated message from the Apache Git Service.
