Breaking: #69699 - TCA ctrl typeicons removed 

See forge#69699

Description 

The TCA['ctrl']['typeicons'] key has been removed.

Impact 

If still used, a fallback default icon may be displayed instead.

Affected Installations 

Searching for typeicons keyword should reveal extensions using this functionality.

Migration 

Until further works on the icon API have been finished, TCA['ctrl']['typeicon_classes'] should be used as documented in the TCA reference.
