QWidgetRepaintManager: Use textureChildSeen to determine deferred update 

We want to get rid of the QWindowPrivate::compositing member, as it is
no longer needed for the Android backingstore, which it was first added
for in a4f50269f8.

We can use textureChildSeen instead to check if we're compositing.

Pick-to: 6.7
