T61971: Compilation Displacement/Background Kernel

Browse Source 
Displacement and Background kernels are selectively used, but always compiled. This patch will not compile these kernels when they are not needed.

Displacement kernel is only used for true displacement.
Background kernel is only used when there is a (Cycles)Light of type `LIGHT_BACKGROUND`.
