QAbstractItemView: don't start editing on Ctrl-Click

Amends 17c1ebf8bfd254ff75cc55e335d1c1fb01da547f, after which dragEnabled
item views toggled selection on click rather than on press. If the edit
trigger included SelectedClicked at the same time, then Ctrl-Clicking a
selected item would start editing the item, instead of toggling
selection.

Fix this by ignoring clicks with modifier when evaluating whether
editing should start.

Extend the mouseSelection test case by including a column for the
editTrigger, and cover the respective combinations.

Fixes: QTBUG-111131
Pick-to: 6.5 6.4 6.2
