VoxelManipulator code cleanup (#15114)

Browse Source 
* Cache node in voxel area index when possible

The index function according to the MSVC profiler actually takes up a significant time slice (around ~5% of total time for the process) during normal game-play.
Might not be accurate but still good to not recalculate it twice.

* Remove `setNodeNoRef` from VM

* VM: remove old commented out print statement
