[ML-11878](https://iguazio.atlassian.net/browse/ML-11878) Enables streaming (generator-based) runnables to work with process_pool and dedicated_process execution mechanisms. Since generators cannot cross process boundaries directly, this implementation uses multiprocessing queues to transfer chunks from child processes to the parent: * Child process iterates the generator and sends chunks via queue * Parent process yields chunks from a queue-reading generator * Errors are serialized and re-raised in the parent as RuntimeError Changes: * `_streaming_run_wrapper` / `_static_streaming_run` - execute streaming runnables in child process `_read_streaming_queue` / `_async_read_streaming_queue` - yield chunks from queue in parent * Lazy-initialized `multiprocessing.Manager` for queue creation * Comprehensive test coverage for all execution mechanisms
