Pcbnew VRML export all internal copper layers
Description
The current VRML exporter only exports the top and bottom layers, for the multi-layer PCBs the internal layers are not exported.
It would be very useful to export the internal copper layers, this will be useful in other tools such as Blender and FreeCAD to perform simulations such as DC current distribution and power integrity. See this tweet which shows using Blender's geometry nodes to solve the Laplace equation to determine the current distribution in copper planes
