[TASK] Remove all code occurrences from showRemovedLocalizationRecords

The TCA option showRemovedLocalizationRecords was former used to enable
showing 'dangling' records (localized records without parent). Because
it was subject to a broken db structure, its usage was removed in patch
f6f36d3f. But there was still code mentioning this key without using it.

A TCA migration removes this option and logs a message which pinpoints
the lack of usage.
