Cycles: Generate OSL closures using macros and a template file

This has the advantage of being able to use information about the
existing OSL closures in various places without code duplication. In
addition, the setup code for all closures was moved to standalone
functions to avoid usage of virtual function calls in preparation for GPU
support.

This patch was split from D15902.
