    ByteArray: Implement ByteArray.toGBytes() in JS
    
    At least from what I can tell ByteArray.toGBytes() doesn't support
    ByteArray.ByteArray instances and at some point the GLib.Bytes constructor
    started working to copy data just fine.
    So now toGBytes() is just a wrapper around GLib.Bytes and I removed
    _makeBytes().
