Make an assessment on whether the mesh needs to be continuously updated in the ARCameraView or can be done right at the capture

Unless we are using the mesh for visualization, I don't see why we need to waste compute in updating the polygon mesh all the time.
If we are only using it for sidewalk attribute calculation after the capture we don't need to do the continuous update.

Currently, the only visualization I see that may be needed is for marking deviant polygons (for surface integrity) as red for viewer's understanding.
