Dynamic Entity Reference now supports entity field query

After Entity query allows to specify entity type ID for reference fields, Dynamic Entity Reference supports entity field query.

For example, with dynamic entity reference field der_field on node which can reference users and taxonomy terms.

To find all the nodes referencing user foo.

Drupal::entityQuery('node')
  ->condition('der_field.entity:user.name', 'foo', '=')
  ->execute();

To find all the nodes referencing taxonomy term bar.

Drupal::entityQuery('node')
  ->condition('der_field.entity:taxonomy_term.name', 'bar', '=')
  ->execute();
