c20488ce - skip_infer for SkipGroupNorm in SymbolicShapeInference (#18630)

skip_infer for SkipGroupNorm in SymbolicShapeInference (#18630) ### Description <!-- Describe your changes. --> https://github.com/microsoft/onnxruntime/pull/18273 added `SkipGroupNorm` contrib op but it did not skip onnx shape inference for this op in `SymbolicShapeInference`. This leads to failed shape inference of the transformers optimized model with `enable_skip_group_norm=True`. Also results in an invalid float16 model for the SD CUDA example. This PR adds `SkipGroupNorm` to `skip_infer` so that it skips onnx shape inference for this op and instead uses the relevant dispatcher. ### Motivation and Context <!-- - Why is this change required? What problem does it solve? - If it fixes an open issue, please link to the issue here. --> Fix shape inference failure for models with `SkipGroupNorm` nodes.
