Fix a bug in SkGpuBlurUtils::GaussianBlur (take 2)
This fixes the remaining imageblurclampmode bug and a preexisting un-reported error in the imageblurrepeatmode GM.
This relies on https://chromium-review.googlesource.com/c/chromium/src/+/1044113 (Add a flag to disable a blur imagefilter bug fix in Skia) landing in Chrome first.
Bug: skia:7765
