Rename the files and classes required by the OpenCL GEMM heuristic

All existing kernel type selection heuristics
CLGEMMKernelSelection<Architecture> are renamed to
CLGEMMDefaultType<Architecture>

All existing kernel configuration heuristics
CLGEMM<KernelType>KernelConfiguration<Architecture> are renamed to
CLGEMMDefaultConfig<KernelType><Architecture>

This refactoring is required to make room for tuner-based heuristics
