Accept a mouse event's point if event is accepted after visiting item

When event handling code explicitly calls QPointerEvent->setAccepted(),
all points get accepted, because that function is virtual now and makes
it so.  But the event is pre-accepted before delivery, because by
tradition, the item must ignore the event if it doesn't handle it, but
is not required to accept if it does handle it.  Then in
deliverPressOrReleaseEvent() (and other places) we check
allPointsAccepted(), in case the event is a touch event and some item
chooses to handle only a subset of the points.  So it was not OK to
remove this line that keeps them in sync after tradtional mouse
delivery, which was added in 47ee54455beb1a063515041f85b4c216132491b3.
The result was that delivery "kept going" past items that would neither
accept() nor ignore() the mouse event, such that items further down
could steal the grab, etc.  In this case it was the ComboBox itself
that received the press event, stole the grab from the TextField,
and so the TextField did not get the mouse move and release that
would select a range of text.
