Add negate and and/or functionality to order product category condition

Patch #10 seems to have no effect on Commerce 2.36. The new select field "condition" doesn't works.

Added tests for new functionality but they fail for a reason I don't understand.

Drupal\Tests\commerce_product\Unit\Plugin\Commerce\Condition\OrderItemProductCategoryTest::testEvaluate
TypeError: array_intersect(): Argument #1 ($array) must be of type array,
null given

I'm guessing it's taking issue with
$configuration['terms'] = ['62e428e1-88a6-478c-a8c6-a554ca2332ae', 'a019d89b-c4d9-4ed4-b859-894e4e2e93cf'];
as it says it's supposed to be an array but null was given instead?

The operators didn't work for me either. I ended up trying to write a custom condition that negates the default one commerce provides. Which turned out to be very easy:

<?php

namespace Drupal\MODULE\Plugin\Commerce\Condition;

use Drupal\commerce_product\Plugin\Commerce\Condition\OrderItemProductCategory;
use Drupal\Core\Entity\EntityInterface;
use Drupal\Core\Plugin\ContainerFactoryPluginInterface;

/**
 * Provides the product category negated condition for order items.
 *
 * @CommerceCondition(
 *   id = "order_item_product_category_negated",
 *   label = @Translation("Product category negated"),
 *   display_label = @Translation("Product categories negated"),
 *   category = @Translation("Products"),
 *   entity_type = "commerce_order_item",
 * )
 */
class OrderItemProductCategoryNegated extends OrderItemProductCategory implements ContainerFactoryPluginInterface {
  /**
   * {@inheritdoc}
   */
  public function evaluate(EntityInterface $entity) {
    return !parent::evaluate($entity);
  }

}

Maybe we could even use that for this issue?
