QWidgetRepaintManager: Use textureChildSeen to determine deferred update

Browse Source 
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 a4f50269f82695fbd0dd344f87b4b355feff4333.

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