Note, at first this seems to not be working, but it is because the
default grease pencil geometry all on the XZ axis.

Rotating the geometry in X 90 degrees shows the mesh.

Part of #113602.

Array<Mesh *> mesh_by_layer(grease_pencil.layers().size());
...
      mesh_by_layer[layer_index] = mesh;

Might be nice if the number of instances always matches the number of layers. That means some instances have to reference empty geometry.

It would be nice to only generate the empty instance handle (InstanceReference::Type::None / InstanceReference{}) if there's an empty layer

Just two picky comments inline. It would also be nice to mention the instances thing in the commit message or just link to the conversion design task where we can mention it.

Invert this to handle the !mesh case first. It's more typical to continue or return early in the null/unexpected/empty case
