TypedData instances created by TypedConfigManager::createFromNameAndData() are incomplete

Problem/Motivation

#2869809: Make it easy to get typed config representations of entities introduced \Drupal\Core\Config\TypedConfigManager::createFromNameAndData():

  public function createFromNameAndData($config_name, array $config_data) {
    $definition = $this->getDefinition($config_name);
    $data_definition = $this->buildDataDefinition($definition, $config_data);
    return $this->create($data_definition, $config_data);
  }

It's great! It's used in many places.

But it has one bug: the \Drupal\Core\TypedData\TraversableTypedDataInterface instances it returns do not have a working getName() nor a working getPropertyPath(), because we forgot to pass the third argument to ::create(): public function create(DataDefinitionInterface $definition, $value = NULL, $name = NULL, $parent = NULL) { — the $name!

Steps to reproduce

N/A — discovered in #3216089: Expose validation constraints (and validatability %) in Config Inspector UI.
