comfyanonymous bf4c9a08fc Implement comfy kitchen attention. (#15479) ...

Add a ModelAttentionBackend node to manually select the attention for models in the workflows. Currently supports pytorch attention or comfy kitchen attention.

Add --use-ck-attention to enable comfy kitchen attention as the default attention backend for all models (might break some).
