Reverting for now. 

I think it's either a matter of (a) updating the caster in PybindAdaptors.h so that it can interpret `MlirOperation` as reference when the corresponding operation itself (and maybe one of its ancestors) is already owned by python or (b) somehow providing a mechanism for downstream binding implementers to indicate whether they intend to transfer ownership. But I'm rusty on this whole ownership business.
