Add support for real time geometry nodes

[kaosat-dev]

Not trivial to implement, so this is a longer term project, but it would be great to have the ability to have Geometry Nodes inside Bevy. I Would love to be able to directly use , adjust, transform geometry node based modeling/animation inside Bevy ! The aim would be a "good enough" implementation in Bevy + the ability to export geonodes from Blender in a transparent way (much like the rest of the gltf workflow).

• currently for gltf, modifiers are applies by default, but we want the actual graph, relatively easy to extract using Blender's python api
• on the Bevy side, we would need at least a few of the nodes to be re-implemented and hooked up with various systems & components

A question does blenvy support normal geometry types? i have trouble adding them.

A much simpler target would be just supporting rastering geometry nodes + modifiers prior to exporting.
