Description

after pressing "interrupt" button, for example inside inpaint tab, upscaling with ai still will be used, if opts.upscaler_for_img2img is overridden. It takes a ton of time for upscaling e.g. 512p -> 4k, especially for DAT upscalers. It can be stopped only is server is stopped

I've added two checks for interruption flag inside do_upscale and upscale. It still upscales images, but with Lanczos
