Feature: #89032 - Render fieldControl for SelectSingleElement 

Description 

The missing rendering for the fieldControl option for SelectSingleElements was added.

Impact 

It is now possible to use the fieldControl option for SelectSingleElements to add nodes and wizards.

For example, add a link popup button to a select called "field_name" of the pages table:

$GLOBALS['TCA']['pages']['columns']['field_name']['config']['fieldControl']['linkPopup'] = [
 'renderType' => 'linkPopup',
];
