Particularly hard-to-understand areas deserve good in-line documentation. - Include changes and enhancements to the documentation (in site/content/in-dev/unreleased) - For Work In Progress Pull Requests, please use the Draft PR feature.

Streamlining Event-to-JSON Serialization: The previous architecture involved a redundant, two-step conversion process: events were transformed into intermediate Maps by an abstract class, and only then was the resulting map serialized into JSON (as seen in AwsCloudWatchEventListener). Since Jackson JSON is our chosen serialization format, we've removed this unnecessary intermediate mapping step. We introduced Jackson Mixins to provide native JSON serialization support directly on the event objects. This refactoring simplifies the serialization pipeline from: Event -> Map -> JSON to Event -> JSON 2. Introduces `AllEventsForwardingListener`, a generic event listener designed to automatically receive and forward all Polaris events without requiring explicit event-type configuration. 3. Introduces `polaris.event-listener.aws-cloudwatch.event-types` property: This property introduces a configurable event filter for the AWS CloudWatch event listener. It defines which Polaris event types should be serialized and forwarded to CloudWatch Logs. <!-- Please clarify what changes you are proposing. The purpose of this section is to outline the changes and how this PR fixes the issue. If possible, please consider writing useful notes for better and faster reviews in your PR. See the examples below. 1. If you refactor some codes with changing classes, showing the class hierarchy will help reviewers. 2. If you fix some IRC features, you can provide some references of other IRC implementations / IRC spec. 4. If there is design documentation, please add the link. 5. If there is a discussion in the mailing list, please add the link. --> ### Why are the changes needed? <!-- Please clarify why the changes are needed. For instance, 1. If you propose a new API, clarify the use case for a new API. 2. If you fix a bug, you can clarify why it is a bug. --> ### Does this PR introduce _any_ user-facing change? <!-- Note that it means *any* user-facing change including all aspects such as new features, bug fixes, or other behavior changes. Documentation-only updates are not considered user-facing changes. If yes, please clarify the previous behavior and the change this PR proposes - provide the console output, description and/or an example to show the behavior difference if possible. If possible, please also clarify if this is a user-facing change compared to the released Polaris versions or within the unreleased branches such as master. If no, write 'No'. --> ### How was this patch tested? <!-- If tests were added, say they were added here. Please make sure to add some test cases that check the changes thoroughly including negative and positive cases if possible. If it was tested in a way different from regular unit tests, please clarify how you tested step by step, ideally copy and paste-able, so that other reviewers can test and check, and descendants can verify in the future. If tests were not added, please describe why they were not added and/or why it was difficult to add. --> ### CHANGELOG.md <!-- If the changes need to be included in CHANGELOG.md, please add a line here and in CHANGELOG.md. --> -- This is an automated message from the Apache Git Service.
