DynamicTreeModel test helper: port away from Q_FOREACH

This source file is included in four other test projects, so it makes
more sense to port it away from Q_FOREACH than to white-list it
everywhere it's used.

The change in ModelMoveCommand::doCommand() is trivial. I only dropped
the pointless top-level const of the loop variable as a drive-by.

The change regarding `parents` in ModelChangeChildrenLayoutsCommand's
doCommand() is also trivial, I just ported to braced initialization to
get the QList to be const. We're forced by the Qt API
(layoutChanged()) to use a QList here, therefore no array.

Ibid., the change regarding `persistent` is simple. The container
cannot be marked as const without a lot of churn to its initialization
(applying IILE, basically), but other than that, it's a local
variable, and the loop body clearly doesn't modify it.

Task-number: QTBUG-115839
Pick-to: 6.6 6.5
