rework Negative Guidance minimum sigma to work with AND, add infotext and copypaste parameters support

rename CPU RNG to RNG source in settings, add infotext and parameters copypaste support to RNG source

Makes a given manual seed generate the same images across different
platforms, independently of the GPU architecture in use.

Fixes #9613.

If image_cfg_scale is =1 then the original image is not used for the output. We can then use the original CFGDenoiser to get the same result to support AND functionality.

Maybe in the future AND can be supported with "Image CFG Scale"
