    scripts/ext-tools: introduce new script to install prebuilt tools
    
    Add a simple script to make it easier to install a prebuilt tools tar.
    Currently it will be used by our tools container and kernel workflow on
    github.
    
    Simple script that take a tar that contains prebuilt host tools, extract
    them and refresh the timestamps to skip recompilation of such host
    tools.
    
    By default it refresh timestamps of build_dir/host and
    staging_dir/host/stamp.
