Remove ChillEventBundle and refactor framework.yaml configurations

This commit involves the deletion of ChillEventBundle from the bundles configuration. Additionally, test framework configurations are handled in a consolidated manner by moving assets configurations (json_manifest_path) from test/framework.yaml to framework.yaml. The obsolete test/framework.yaml has been deleted as it is no longer needed.
