Support Wan2.2-Animate #12441

Wan2.2-Animate-14B, it's a unified model for character animation and replacement, with holistic movement and expression replication.

We would like open to the community, if anyone is interested, to integrate this model with Diffusers. Just take into consideration these points:

1. Don't integrate the preprocessing, we can help with that using a modular custom block.
2. This issue is for more advanced users than know the diffusers library very well.

Just let me know that you're interested and if you have any doubts, feel free to ask, if you open a PR we can help but we are currently busy with other priorities so we ask you to be patient.
