Log Event Trigger Capability Development: Part 2 (#14609)

* Receive log as values.Value to preserve type info

* Test cursor usage of LogEventTrigger capability

* Added JSON schema for log event trigger capability

* Remove old override and generate log event capability

* Update JSON schema constraints

* Use types from generated pkg to reduce code duplication

* Generate SDK helper after JSON schema change
