Merge with extra: opencv/opencv_extra#906

This PR adds test for #19877 by @erikguo, which implements new_coords for YOLOv4x-mish in CPU mode, fixing #18975.
The golds were obtained from OpenCV itself after I compared resulting boxes and probabilities of classes after NMS from Darknet and OpenCV. Boxes' coordinates in range [0-1] differ in 5th decimal place, probabilities(0-1) in 4th.

relates #19876
