Add dnn_classify filter support to the ONNX Runtime DNN backend so classification inference can run with ONNX models. Classifier outputs of rank 2 [N,C] and rank 1 [C] are promoted to [N,C,1,1], since common classification models produce these shapes. The output batch dimension is validated to equal 1 before post-processing. Fix a deadlock when a frame has no bounding box to classify: the request is returned to the queue instead of being destroyed, and the lltask queue is checked before popping a request. Frames with multiple bounding boxes are handled by looping through all queued lltasks in execute_model_onnx. Bounding box boundary checks use > instead of >=, so a box ending exactly at the frame edge is no longer rejected.
