QPolygonF: delegate QDataStream marshalling to QList

Browse Source 
Like the QPolygon code. This fixes a mistake in failing to clear the
list before de-marshalling in operator>>.

Updated most of the QDataStream tests to have data in the objects
they're streaming into, to ensure that the stream overwrites everything.

Fixes: QTBUG-122684
Task-number: QTBUG-122704
Pick-to: 6.6 6.5 5.15
