It's not the software that holds back phone cameras. It's the literal size and shape of the sensors and lens.

You can already shoot RAW on a phone, but putting Photoshop on the phone won't solve the lack of depth of field inherent to the lens and sensor setup.

Does the RAW format save the kind of information that the software uses to guess at bokeh (depth sensors, multiple lenses, multiple shots, defocused pixels)? Or is there some other format that could save all that info, so you could really use the phone but do the processing later?

There’s no, but there isn’t really a need. The R package mentioned in a comment in this thread achieves a similar effect using no additional data.

Ray tracing will suffice!

It shows a hand made depth map. You can't just 'raytrace' a 2D image and magically add depth of field.
