[pim/kcalutils] src: Replace most iCal QMimeData en/decoding API with KCalendarCore::MimeData

Git commit 1b167c95a08230cb86ba899afc5d0eaec977981f by Volker Krause.
Committed on 28/07/2026 at 16:03.
Pushed by vkrause into branch 'master'.

Replace most iCal QMimeData en/decoding API with KCalendarCore::MimeData

The remaining methods have one user each and will be used there, entirely
removing DndFactory as well.
