T61463: Separate Baking kernels
Cycles OpenCL: Split baking kernels in own program
Fix T61463. Before this patch baking was part of the base kernels. There
are 3 baking kernels that and all 3 uses shader evaluation. Only for one
of these kernels the functionality was wrapped in the __NO_BAKING__
compile directive.
When you start baking this leads to long compile times. By separating
in individual programs will reduce the compile times.
Also wrapped all baking kernels with __NO_BAKING__ to reduce the
compilation times.

I don't have a grounded explanation why koro and volume_emission is this much
faster; I have done several tests though...
