Creates ClKerneLibrary to serve just as a kernel container without build logic

Moves all the kernels out of the legacy CLKernelLibrary into a separate
class that its planned responsibility is to only handle the kernel
strings.

Currently CLKernelLibrary mixes kernel inventory and building logic,
thus coupling multiple responsibilities.
By separating compilation logic, the kernel library removes any dependencies
from the OpenCL and simplifies maintainance but also increases flexibility.
