RFC: lavapipe: disable AOS sampling on CI
So, ugh. This isn't great, but...
It seems like the AOS sampling stuff isn't precise enough to pass the VK CTS. Which is silly, because the Vulkan spec explicitly expects the interpolation to happen in fixed-point coordinates etc.
So unless there's some bug or missing feature in the code here, it doesn't seem like we should have to do this.
Yuck, but it's unclear to me how to get around this.
Contains !12233 (closed), just to avoid getting a conflict once that fails.
