Don't emit change notifications more often than required
When a property value changes, first update all dependent bindings to
their new value. Only once that is done send out all the notifications
and changed signals.
This way, if a property depends on multiple other properties, which all
get changed, there will only be one notification; and (potentially
invalid) intermediate values will not be observed.
Fixes: QTBUG-89844
