Title: Added WithIdleOverlay Render Trait

This does the easiest yet most common variant of #2211. It will help me complete setup the Tiberian Sun buildings properly and is also required for Dune 2000. I did not clean up and finish the d2k mod overlays yet because @pchote blocked #3676 and I won't do all the manual overlay offset tweaking twice.
