[FLINK-37837][core] Always add create.table to include.schema.changes option

[Hisoka-X]

This close https://issues.apache.org/jira/browse/FLINK-37837

This pull request ensures that the CreateTableEvent is always included in the set of schema change events unless the user explicitly excludes it. This change guarantees the foundational event is present for proper schema evolution handling.

I think that always add create.table to include.schema.changes option is not a good idea ,because user can create table without flink-cdc and others

Users can set create.table into exclude.schema.changes.

I think this is the correct processing logic, if users always create tables first, and creating tables may be a failure that leads to task failure.
