Subject: [PATCH 06/28] QQuickWindow: Check if QQuickItem was not deleted

Added check into deliverMatchingPointsToItem method for Android device.

In QT_VERSION below 6.0.0 touchEnabled for QtQuickItems is set by default to true
It causes delivering touch events to Items which are not interested
In some cases it may cause a crash. For example using Material Style in Android.
QQuickShaderEffectSource may be deleted and then try to handle touch

Fixes: QTBUG-85379
