[TASK] Category fields are not added to TCA interface section

$TCA[<table>]['interface']['showRecordFieldList'] contains a list
of fields that is used for visualizing
* accordant element details (record info)
* differences in the workspaces detail view

Fields that are treated as category should appear automatically.
If using CategoryRegistry::add() in extensions, the option
property "interface" can be used to disable this automated
handling in the interface section - in that case it needs
to be FALSE.
