testing: Adjust test comparision thresholds for Mac ARM (#5026)

Even though we have CI testing on Mac with ARM CPU that were passing,
after getting a new laptop, I saw some test failures that were due to
just a few pixels on a few tests needing a higher comparision threshold.
Results are correct, just different due to the math. I guess this
machine (CPU? build flags? specific compiler or library versions?) is
ever so slightly different than the CI Macs, so I caught a few more
instances that needed to be adjusted.

I tried to increase the thresholds as little as possible to fix the
problem.
