Benchmark CI: skip unsupported SYCL SinKernelGraph graph-mode cases on PVC

[Copilot]

The [PR] Benchmark suite testing / Framework test only: L0, Minimal preset, dry-run job failed because graph_api_benchmark_sycl was invoked with --withGraphs=1 on PVC, where graph record/replay is unsupported and aborts under --exit-on-failure.
This PR narrows benchmark scheduling so unsupported SYCL graph-mode variants are not selected on that platform.

• Root-cause alignment

  • In ComputeBench.benchmarks(), GraphApiSinKernelGraph(..., with_graphs=1, ...) is now skipped when:
    • runtime is in SYCL_RUNTIMES
    • adapter is level_zero_v2
    • detected device architecture contains pvc

• Selection logic change (minimal scope)

  • Existing adapter-based SYCL graph gating remains intact.
  • New PVC guard applies only to the failing graph-mode path (with_graphs == 1), leaving non-graph (with_graphs == 0) cases unchanged.

• Targeted coverage

  • Added devops/scripts/benchmarks/tests/test_compute_bench.py checks for:
    • SYCL graph-mode excluded on PVC
    • SYCLPreview graph-mode excluded on PVC
    • SYCL graph-mode retained on non-PVC

if (
    "pvc" in device_arch
    and options.ur_adapter == "level_zero_v2"
    and runtime in SYCL_RUNTIMES
    and with_graphs == 1
):
    continue
