function price_form_views_ui_config_item_form_alter in Price 2.0.x

Implements hook_form_FORM_ID_alter().

Removes the "Calculated price" formatter from views field options, if it is not applicable. Since the formatter is entity specific, this prevents it from accidentally being used on other entity types.

@todo Remove when https://www.drupal.org/node/2991660 gets fixed.
