[Feature Request] Implement GroupNormalization-21 #22697
Description
Describe the feature request
A corrected version of GroupNormalization is release in opset21. It will start appearing in new models. We should have support for it. Most likely the kernels are already implemented and we just need to register the op. https://onnx.ai/onnx/operators/onnx__GroupNormalization.html#l-onnx-doc-groupnormalization
Describe scenario use case
New ops support.
