  Initialize the browser to display the specified configuration forms.\r

  This function is the primary interface to the internal forms-based browser.\r

  The browser will select all forms in packages which have the specified Type\r
  and (for EFI_HII_PACKAGE_TYPE_GUID) the specified PackageGuid.\r
