Create sniff for missing @param directive when other @param tags exist

This is a spin-off from #2621486: Fixes to migrate/tests/src/Unit/*.php files. In that issue, the constructor() method of core/modules/migrate/tests/src/Unit/TestSqlIdMap.php was corrected by hand for the missing @param directive for the final variable $event_dispatcher. For some reason, the FunctionCommentSniff.php sniff is not catching this missing @param directive.

Good example:

  /**
   * Constructs a TestSqlIdMap object.
   *
   * @param \Drupal\Core\Database\Connection $database
   *   The database.
   * @param array $configuration
   *   The configuration.
   * @param string $plugin_id
   *   The plugin ID for the migration process to do.
   * @param mixed $plugin_definition
   *   The configuration for the plugin.
   * @param \Drupal\migrate\Entity\MigrationInterface $migration
   *   The migration to do.
   * @param \Symfony\Component\EventDispatcher\EventDispatcherInterface $event_dispatcher
   *   The event dispatcher service.
   */
  public function __construct(Connection $database, array $configuration, $plugin_id, $plugin_definition, MigrationInterface $migration, EventDispatcherInterface $event_dispatcher) {
  }

Bad example:

  /**
   * Constructs a TestSqlIdMap object.
   *
   * @param \Drupal\Core\Database\Connection $database
   *   The database.
   * @param array $configuration
   *   The configuration.
   * @param string $plugin_id
   *   The plugin ID for the migration process to do.
   * @param mixed $plugin_definition
   *   The configuration for the plugin.
   * @param \Drupal\migrate\Entity\MigrationInterface $migration
   *   The migration to do.
