Trigger Filters

• The new-trigger-filters feature flag has been removed, and the feature is now GA and always enabled. (#3963, @Cali0707)
• The CESQL filter dialect now supports the CESQL v1 specification (https://github.com/cloudevents/spec/releases/tag/cesql%2Fv1.0.0). IMPORTANT: The v1 specification has some changes compared to the previous v0.1 - please verify your expressions if you use CESQL filters (#3964, @Cali0707)
