Cycles: Pass Blender's C++ RNA structures by reference

This way we avoid passing structures which could be up to
few hundred bytes by value to the utility functions.

Ideally we'll also have to add `const` qualifier in majority
of the calls, but C++ RNA does not allow us to do that because
it does not know if some function modifies contents or not.
