P: (Masking) (AI) generated depth map for depth masks

The new lens blur function generates a depth map from images without depth information.

It would be nice to be able to use this depth map for mask creation.

Right now only lumance and color range is support here, but depth range is disabled if the image doesn't contain a depth map. In this case an AI generated depth map could be used to enable depth range based masks even if no depth data is recorded in the image.
