[FEATURE] Introduce shadowColumnsForMovePlaceholders property

$TCA[<table>]['ctrl']['shadowColumnsForMovePlaceholders'] behaves
similar to shadowColumnsForNewPlaceholders but is only used for
move placeholders.

If shadowColumnsForMovePlaceholders is not defined in particular
for a table, but shadowColumnsForNewPlaceholders is defined,
then that value is used as a fallback - since that property
existed for a longer time already.
