Fix #36408: Setting `image.colorspace_settings.name` changes saved alpha
Issue was caused by reload caused by input colorspace change.
For generated images generated alpha flags weren't saved to
DNA, which lead to fallback from 32 bit depth to 24 when
doing any kind reload of generated image.
The same alpha loss happens when you save .blend file with
generated images.
Now added generated depth to DNA, so reload image and .blend
file wouldn't loss alpha.
