Skip pytorch_CycleGAN_and_pix2pix from inductor benchmarks (#175066)
Summary:
## Summary
Skip the `pytorch_CycleGAN_and_pix2pix` benchmark model from the inductor benchmark suite.
This legacy 2017 model has been failing with `eager_fail_to_run` on 100%
of commits since mid-2025, providing zero CI signal while consuming
~5.3M GPU-seconds/week across 7+ benchmark jobs on CUDA, CPU, and ROCm.
**Estimated savings: ~310 GPU-hours/week (~1,240 GPU-hours/month)**
Skip it in `torchbench.yaml` and remove its entries from all 31 expected
accuracy CSV files. Also remove it from the `higher_fp16` tolerance list.
See P2188981399 for the full CI workflow analysis.
## Test Plan
- CI should pass with CycleGAN skipped (it was already failing 100% of the time)
- No other benchmark models affected
