* yolov5 use external stream * yolov5lite/v6/v7/v7e2etrt: optimize output tensor and cuda stream * avoid reallocating output tensors * add input output tensors to FastDeployModel * add cuda.cmake * rename to reused_input/output_tensors * eliminate cmake cuda arch error * use swap to release input and output tensors Co-authored-by: Jason <jiangjiajun@baidu.com>
