Erik Abrahamsson 31e61f84a6 Fix #106776: Volume cube won't render in Cycles 
In some cases the Geometry Nodes Volume Cube generates
a Volume grid that doesn't contain any leaf nodes. This can happen
when only tiles are needed to represent the volume.

This PR changes the `empty_grid` check function to also check if there
are any active tiles in the grid before returning `true`.
