Adding the ability to specify js libraries that need to be loaded with js runtime running kernel code. This change alters the structure of mainfest.yml for all three projects by adding features and kernel_libs as two distinct sections. Any files added in kernel_libs will be added to load_file.txt for all platforms and will be loaded while initializing the js runtime for kernel code.
