Perform masked image restoration for GFPGAN, RealESRGAN, fixing #947
Also fixes bug in image display when using masked image restoration with RealESRGAN.
When the image is upscaled using RealESRGAN the image restoration can not use the original image because it has wrong resolution. In this case the image restoration will restore the non-regenerated parts of the image with an RealESRGAN upscaled version of the original input image.
Modifications from GFPGAN or color correction in (un)masked parts are restored to the original image by mask blending.
