Add SkipGroupNorm Contrib Op

[TedThemistokleous]

DOR (Definition of Ready)

When we have a change and need to find additional optimizations for stable diffusion pipelines that leverage Onnxruntime as the front end.

Description

Task

Add support for the Microsoft Contrib op SkipGroupNorm Doc: https://github.com/microsoft/onnxruntime/blob/main/docs/ContribOperators.md#com.microsoft.SkipGroupNorm

Uses

Seen in Stable diffusion optimizations with Onnxruntime's pipeline's

Seen via using the optimize pipeline script for stable diffusion runs

export MIGRAPHX_DISABLE_CK_GEMM=1
export MIGRAPHX_DISABLE_CK_GEMM_FUSION=1
export MIGRAPHX_DISABLE_CK_GEMM_SOFTMAX_GEMM=1

python optimize_pipeline.py  -i ./sd-v2 -o ./sd-v2-0-migx --float16 --disable_attention  --disable_skip_layer_norm   
--disable_embed_layer_norm --disable_bias_skip_layer_norm  --disable_nhwc_conv   --disable_group_norm 

Reference to the workflow on this found here: https://github.com/ROCm/AMDMIGraphX/issues/1688

Using this would give us the ability to further parse OnnxRT optimizations prior to MIGraphX doing any sort of optimizations

DOD (Definition of Done)

• [ ] Operator is parsed in MIGraphX-driver correctly
• [ ] Proper test coverage for operator is given in MIGraphX unit tests
• [ ] Onnxruntime support for operator is present when using MIGraphX Execution Provider
