Description
🚀 The feature
Native box_area and box_iou functions for cxcywh format.
Motivation, pitch
Since the cxcywh format is common, we can use faster and simpler functions to calculate box area and box IoU directly in this format.
Currently, we first need to convert to the xyxy format before using box_area and box_iou in torchvision.

Research direction
Locate the existing box_area and box_iou implementations in torchvision and inspect how box formats are handled. Compare the requested cxcywh behavior with the current xyxy conversion path; done means native cxcywh area and IoU functions are available and their results are validated.
