Use a set of pre-tuned configs as default config if auto-tuning is disabled. These configs are tuned for Intel GPU with 48/72 EUs, and for googlenet, AlexNet, ResNet-50 If default config is not suitable, use the first available kernel config from the candidates. Candidate priority from high to low is gemm like kernel, IDLF kernel, basick kernel. * dnn(ocl4dnn): pooling doesn't use OpenCL subgroups * dnn(ocl4dnn): fix perf test OpenCV has default 3sec time limit for each performance test.
