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.

Impact on render time

--------+-----------------+----------+---------+------------
T61463 | empty | 21.06 | 20.54 | 2%
T61463 | bmw | 198.44 | 189.59 | 4%
T61463 | fishycat | 394.20 | 388.50 | 1%
T61463 | barbershop | 1188.16 | 1185.49 | 0%
T61463 | classroom | 341.08 | 339.27 | 1%
T61463 | koro | 472.43 | 360.70 | 24%
T61463 | pavillion | 905.77 | 902.14 | 0%
T61463 | splash279 | 55.26 | 54.92 | 1%
T61463 | volume_emission | 62.59 | 39.09 | 38%

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