In order to integrate Drag & Drop with NativeFileSystem,
 we need to have a DataObjectItem own a remote to a
 NativeFileSystemTransferToken. A JavaScript exposed
function will then take the remote NativeFileSystemTransferToken,
redeem it for a NativeFileSystemFileHandle or
 NativeFileSystemDirectoryHandle, and expose the
resulting handle to the Web.
