87e5ce35 - Add batch-invariant accuracy mode for benchmark perf tests (#180610)

Add batch-invariant accuracy mode for benchmark perf tests (#180610) Summary: Adds a new `--batch-invariant` accuracy mode to the dynamo benchmark harness and wires it into the nightly H100 inductor dashboard. For a model with full batch size N, the mode runs the compiled forward at N, N/2, N/4, ..., 1, and for each smaller size checks that the output is bitwise equal to the full-batch reference sliced down to that size. A The plan is to land this first so we have continuous dashboard signal, then drive model pass-rates up by fixing the underlying inductor issues model-by-model. CI: - `.ci/pytorch/test.sh` dispatches the accuracy run whenever `DASHBOARD_TAG` contains `batch_invariant_accuracy-true`.
