Drop TCA ctrl typeicons
[TASK] Drop TCA ctrl typeicons
The typeicons key in TCA ctrl section was deprecated for a
long time already and marked as "use typeicon_classes" instead
within the documentation.
The patch drops last usages in core TCA - they all overlap with
typeicon_classes already and drop the handling.
