Problem/Motivation
The interface \Drupal\Core\TypedData\DataDefinitionInterface is missing the setConstraints() method that is defined in the \Drupal\Core\TypedData\DataDefinition::setConstraints even with the {@inheritdoc} tag. The method is present in the \Drupal\Core\Field\FieldConfigInterface::setConstraints for example, and I think it should be moved to the DataDefinitionInterface instead.
Proposed resolution
Add the setConstraints method to \Drupal\Core\TypedData\DataDefinitionInterface.
Remaining tasks
Add the setConstraints method to \Drupal\Core\TypedData\DataDefinitionInterface.
Remove the setConstraints method from \Drupal\Core\Field\FieldConfigInterface::setConstraints
