   * Render API callback: Hides display of the upload or remove controls.

   * Upload controls are hidden when a file is already uploaded. Remove controls
   * are hidden when there is no file attached. Controls are hidden here instead
   * of in \Drupal\file\Element\ManagedFile::processManagedFile(), because
   * #access for these buttons depends on the managed_file element's #value. See
   * the documentation of \Drupal\Core\Form\FormBuilderInterface::doBuildForm()
   * for more detailed information about the relationship between #process,
   * #value, and #access.
   *
   * Because #access is set here, it affects display only and does not prevent
   * JavaScript or other untrusted code from submitting the form as though
   * access were enabled. The form processing functions for these elements
   * should not assume that the buttons can't be "clicked" just because they are
   * not displayed.
   *
   * @see \Drupal\file\Element\ManagedFile::processManagedFile()
