Preparations to deprecate QItemDelegate

QItemDelegate was superseded since Qt4 by QStyledItemDelegate but it
took until Qt6.7 to remove the last occurrences in qtbase.
 - remove unused includes / replace with qabstractitemdelegate.h
 - replace references in the documentation with QStyledItemDelegate
 - adjust the examples and tests to use QStyledItemDelegate

Pick-to: 6.5 6.6
