[Feature] support synchronize multiple table into corresponding paimon table for MySqlSyncTableAction

### Search before asking

- [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar.

### Motivation

Now, users can synchronize one or multiple tables from MySQL into one Paimon table. I think it is necessary to synchronize multiple MySQL tables to the corresponding paimon table

Start by reading the MySqlSyncTableAction entry point and the current single-table synchronization behavior. The issue provides no files, tests, or proposed design, so first determine how multiple MySQL tables should map to corresponding Paimon tables and what test coverage would demonstrate that synchronization is complete.
