This PR facebookincubator/velox#13341 has not been merged, so bypass the operator validation, after it is merged, I will add back.
For GPU task, usually GPU launch one kernel for one GPU, and Spark workload is big dataset, the GPU memory is not enough for parallel task.
With this restriction

✅ TPC-DS Q95 Runtime (in seconds) — 8 Cores (T4 / g4dn.2xlarge)

Time CPU Only First Stage CPU+GPU
Total Duration 115 82
Second Stage 113 80
