Fix T69753 Instanced Metaballs not rendering but showing up in Viewport

This hides the original metaballs when they are used in
duplifaces/-verts instancing, and still shows the instanced metaballs.

The visibility of the original metaballs is now determined by the
visibility of the instancer. I'm not too thrilled about this, but at
least it gives users the ability to show/hide the metaballs for
viewport/render.
