    meson: Add wrap file to auto-setup libgd subproject
    
    This is the preferred way to auto-setup subprojects. If you use a git
    submodule, Meson will not know that it should initialize it before
    configuration.
    
    With this wrap file, the specified revision from the specified git URL
    (or tarball, etc) will be cloned (or extracted) into the specified
    directory. For more examples, see:
