Blender doesn't read meta data of images in case they were packed, which make things like image Cryptomatte fail. This is because the image loading code didn't specify meta data reading for packed images, but did for normal images. To fix this, we also specify meta data reading for packed images. And while at it, move all common IB flags in the same like to avoid such differences in the future. Pull Request: https://projects.blender.org/blender/blender/pulls/126602
