Add support for views reference method

Problem/Motivation

If you have a field that is using a view to reference its entities, then you will see this error and no information about the view:

Warning: Undefined array key "target_bundles" in Drupal\field_ui_extras\Plugin\FieldUiExtras\FieldSummary\EntityReference->addBundleLinksToItems() (line 51 of modules/contrib/field_ui_extras/src/Plugin/FieldUiExtras/FieldSummary/EntityReference.php).

Proposed resolution

Add support for this referencing method and a link to the view edit page.
