a95fcb43 - UNet fusion and fp16 conversion for stable diffusion (#14248)

UNet fusion and fp16 conversion for stable diffusion (#14248) Add script to fuse nodes to optimized operators in stable diffusion 1.5 models, and a script to convert fp32 models to fp16 models. Tested with stable diffusion 1.5. Note that the optimized model needs onnxruntime-gpu v1.14 (release candidate will be available soon). Note: We will update the script to work with latest diffusers and stable diffusion v2 and v2.1 models.
