    meson: Port install scripts for cmd.exe shells
    
    On Windows builds using Visual Studio-like compilers, we are using
    cmd.exe shells, so we do the symlinking of the tools and man pages using
    the commands that Windows provides.
    
    Also, group the various programs and man pages together so that we have
    single commands for each of the subdirs that we want to run the install
    scripts, to make things simpler.
