Marking a consistently failing layout test color-profile-image-filter-all.html

virtual/gpu-rasterization/images/color-profile-image-filter-all.html
(likely) started failing from the patch for SlimmingPaintV175. As noted
in the patch, marking it as failing instead of reverting it.

Additionally, marking it as SLOW as it's failing for timeout also on
Mac in addition to Linux and Win which are already specified.
