Run resize in CPU and more aggressively release rknn resources (#1287)

With the latest dev opi image, i saw this stack trace when object detection stopped working (threads hanging forever on detect(). The stack pointed me to somewhere inside the RGA. Based on this i moved resize into CPU (as our [native code already is lazy](6934abb26c/src/main/native/cpp/yolo_common.cpp (L227))), and was not able to see more crashes

Includes also a quick hack to add a shutdown hook that releases pipelines at exit.
