Build a kernel selector tool in Kconfig/bash/python. Implement a naive recommendation algorithm for it. Automatically generate preferences in YAML. The features described in YAML for each kernel is not stable and is only for demonstration currently. Integrate the tool into the Makefile of XiUOS. Run make kernel_selector in XiUOS directory to verify it
