contrib: qtdeclarative: add patch to fix sporadic crash on window move
Targeted for QTBUG-131898 (https://bugreports.qt.io/browse/QTBUG-131898).
Close #28901 (closed). I'm not sure if we should close that issue, maybe we should activate the feature (independent window quick popup) when Qt fixes it as otherwise with non-contrib Qt it can be a problem. I think that it is fair to blame users if they use broken Qt, also considering that this crash is sporadic and rarely happens, thus keep using the feature (!6240 (merged)).
Request review @chub.
