   * Builds a renderable array for the value of a single field in an entity.

   * This function can be used by third-party modules that need to output an
   * isolated field.
   * - Do not use inside node (or any other entity) templates; use
   *   render($content[FIELD_NAME]) instead.
   * - The FieldItemInterface::view() method can be used to output a single
   *   formatted field value, without label or wrapping field markup.
   *
   * The function takes care of invoking the prepare_view steps. It also
   * respects field access permissions.

   *     display settings specified for this view mode in the $field
   *     definition for the field in the entity's bundle. If no display settings
   *     are found for the view mode, the settings for the 'default' view mode
   *     will be used.
   *   - An array of display options. The following key/value pairs are allowed:
   *     - label: (string) Position of the label. The default 'field' theme
   *       implementation supports the values 'inline', 'above' and 'hidden'.
   *       Defaults to 'above'.
   *     - type: (string) The formatter to use. Defaults to the
   *       'default_formatter' for the field type. The default formatter will
   *       also be used if the requested formatter is not available.
   *     - settings: (array) Settings specific to the formatter. Defaults to the
   *       formatter's default settings.
   *     - weight: (float) The weight to assign to the renderable element.
   *       Defaults to 0.
