ed3f8bf1 - Fix build errors of GridSample and test failures in test_attention_fusion.py (#27642)

Fix build errors of GridSample and test failures in test_attention_fusion.py (#27642) # Description This PR addresses a build error and subsequent test failures related to recent changes in GridSample and the transformer optimizer. Related PRs: #27201, #27556. ## Changes ### 1. Fix GridSample Build Error - Removed an unused local variable `mode_str` in `onnxruntime/core/providers/cuda/tensor/grid_sample.cc` that was causing a warning (treated as error) about shadowing a member variable. - Ref: [`grid_sample.cc`](https://github.com/microsoft/onnxruntime/blob/c979a2407f/onnxruntime/core/providers/cuda/tensor/grid_sample.cc#L54) ### 2. Update GridSample Tests - Updated `onnxruntime/test/providers/cpu/tensor/grid_sample_test_custom.inc` to use default execution providers in `RunTests` instead of a hardcoded opset version, ensuring compatibility across different environments. ### 3. Revert Transformer Fusion Fallback - Reverted a recent change in `onnxruntime/python/tools/transformers/fusion_skiplayernorm.py` that enabled a fallback for `SkipLayerNormalization` fusion when symbolic shape inference fails. - This revert was necessary to avoid regressions in GPT-2 tests where model definitions contain typos that intentionally (or coincidentally) break shape inference. - Ref: [`fusion_skiplayernorm.py`](https://github.com/microsoft/onnxruntime/blob/c979a2407f/onnxruntime/python/tools/transformers/fusion_skiplayernorm.py#L113) ### 4. Restore Transformer Test Parity - Updated `onnxruntime/test/python/transformers/test_attention_fusion.py` specifically `test_qwen3_normalization_fusion` to match the expected node counts after reverting the fusion fallback. - Ref: [`test_attention_fusion.py`](https://github.com/microsoft/onnxruntime/blob/c979a2407f/onnxruntime/test/python/transformers/test_attention_fusion.py#L398) ## Verification - `build_cuda.sh` completed successfully. - `onnxruntime/test/python/transformers/test_attention_fusion.py` passes with "OK". - `lintrunner -a` reports no issues.
