[pim/akonadi-calendar] src: Move KCalUtils::DndFactory::copyIncidences here

Git commit 8e8fc92f7dbef8914a298133019ba2ff1695f443 by Volker Krause.
Committed on 29/07/2026 at 19:04.
Pushed by vkrause into branch 'master'.

Move KCalUtils::DndFactory::copyIncidences here

This is the only use, and once we depend on KF 6.29 it's merely 10 lines
of code.
