filter (ticdc): refine filter code

[asddongmen]

What problem does this PR solve?

Issue Number: ref #9876

What is changed and how it works?

1. Modify the eventFilter function to directly return "false" if the user has not configured any eventFilter rules.
2. For certain DDL types that are clear, use the "actionType" directly to determine their type without the need to parse the DDL query using a parser.

Check List

Tests

• Unit test
• Manual test (add detailed scripts or steps below)

Questions

Will it cause performance regression or break compatibility?

Do you need to update user documentation, design documentation or monitoring documentation?
