Win32Platform.Signal should respect DispatcherPriority parameter

Looks like it could easily be encoded in lParam.

I guess I could suggest to write your own queue. Something like

class CallbackQueue
{
    bool _posted;
    Queue<Action> _actions = new();
    
    public void Post(Action a)
    {
         _actions.Add(a);
         if(!_posted)
         {
             _posted  = true;
             DispatcherTimer.RunOnce(() => {
                      _posted = false;
                      while(_actions.Count > 0)
                          _actions.Dequeue()();
             }, TimeSpan.FromMilliseconds(1));
         }
    }
}

DispatcherTimer.RunOnce with 1ms timeout.
