Disable failing Pixel6/Vulkan stablehlo_ops tests again. (#17851)

Patching over the regressions reported here:
https://github.com/iree-org/iree/pull/17843#issuecomment-2221070467

I'm not sure we should still be testing on Pixel 6 though. Might want to
switch to a newer phone or drop those tests down a support level.
