[Feature Request]: SUPIR upscaler

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What would your feature do ?

Integrate SUPIR to the list of current upscalers !

SUPIR code : https://github.com/Fanghua-Yu/SUPIR
ComfyUI node : https://github.com/kijai/ComfyUI-SUPIR

It would be pretty awesome to have this feature in webui :)

### Proposed workflow

Same as current upscalers. In the extra tab and as hi-res fix.

### Additional information

_No response_

No project files or tests are named. Start by reviewing how current upscalers are integrated, then study the linked SUPIR code and ComfyUI node; done means SUPIR is available in the Extra tab and hi-res fix workflow like the existing upscalers.
