Addresses ### Qt 6 comment, and documentation pointing out that the parameter
value is ignored. It wasn't ignored in the code, but that's the kind of change
we can make now.
With this change, QUnifiedTimer::updateAnimationTimers is only called with -1
as the currentTick input parameter, also from Qt Declarative. Make it default,
so that leaf modules can be fixed. Once that it done, the parameter can be
removed completely.
