Patch Release: v0.18.2

Patch release to fix:

• 1. torch.compile for SD-XL for certain GPUs
• 2. from_single_file for all SD models
• 3. Fix broken ONNX export
• 4. Fix incorrect VAE FP16 casting
• 5. Deprecate loading variants that don't exist

Note:

Loading any stable diffusion safetensors or ckpt with StableDiffusionPipeline.from_single_file or StableDiffusionmg2ImgIPipeline.from_single_file or StableDiffusionInpaintPipeline.from_single_file or StableDiffusionXLPipeline.from_single_file, ...

is now almost as fast as from_pretrained(...) and it's much more tested now.
