perf(tests): Spawn image_diff.py only once per job (#13013) c4ea178471
perf(goldens): Spawn image_diff.py only once per job

diff.py was spawning a python process per image, and each re-imported
cv2. This import absolutely DOMINATED the time spent diffing, especially
on Windows. Instead, import cv2 once per job, and diff multiple images
per image_diff.py process.

Time improvement diffing gms on my laptop:   8.7 -> 2 seconds
And diffing gms + goldens:                   26 -> 10 seconds
