Use attribute IDs when getting configurable child products if specified (#24483)

[lfolco]

Description (*)

The method \Magento\ConfigurableProduct\Model\Product\Type\Configurable::getUsedProducts() has an optional parameter, $requiredAttributeIds, that is supposed to add the given attribute IDs to the returned products. This parameter is ignored in the method body.

Fixed Issues (if relevant)

1. Parameter $requiredAttributeIds of getUsedProducts() on configurable product type is not used, custom attribute loading does not work #24483: Parameter $requiredAttributeIds of getUsedProducts() on configurable product type is not used, custom attribute loading does not work

Manual testing scenarios (*)

None. I created two additional integration tests, \Magento\ConfigurableProduct\Model\Product\Type\ConfigurableTest::testGetUsedProductsWithRequiredAttributes and \Magento\ConfigurableProduct\Model\Product\Type\ConfigurableTest::testGetUsedProductsWithoutRequiredAttributes

Questions or comments
