Geometry Nodes: Volume grid Prune and Voxelize nodes

Browse Source 
Add two common building blocks for volume-grid workflows.

- **Voxelize** turns all active tiles into fully dense voxels. For fog
  volumes, this will mean the "inside" sparse tiles will become
  individually adjustable voxel values.
- **Prune** is the opposite action as voxelize. It can be important for
  certain workflows when large regions of constant values are created.
  The node can collapsed those regions into more efficient tiles or
  inner nodes. There are a few modes which are each useful for
  different use cases.
