We only had a very limited, specific handling of that in collection duplication code, but this has to be handled at a much more general level in Object copy code itself, since it makes no sense to duplicate rigidbody object data without adding new copy to relevant rigidbody collections... WARNING: This is a fairly risky rework of rigidbody handling logic when copying an Object data-block. It is *NOT* considered safe enough for 2.80 release. I tried to take into account copy flags to not mess with other IDs (collections) when we are copying outside of Main, and also not do deg tags when this is forbidden, but risk of something going wrong here is too high...
