/**
* Returns the entity_form_display object used to build an entity form.
*
* Depending on the configuration of the form mode for the entity bundle, this
* can be either the display object associated with the form mode, or the
* 'default' display.
*
* This method should only be used internally when rendering an entity form.
* When assigning suggested display options for a component in a given form
* mode, entity_get_form_display() should be used instead, in order to avoid
* inadvertently modifying the output of other form modes that might happen to
* use the 'default' display too. Those options will then be effectively
* applied only if the form mode is configured to use them.
*
* hook_entity_form_display_alter() is invoked on each display, allowing 3rd
* party code to alter the display options held in the display before they are
* used to generate render arrays.
*
* @param \Drupal\Core\Entity\FieldableEntityInterface $entity
* The entity for which the form is being built.
* @param string $form_mode
* The form mode.
*
* @return \Drupal\Core\Entity\Display\EntityFormDisplayInterface
* The display object that should be used to build the entity form.
*
* @see entity_get_form_display()
