Detect orig.Invoke() and orig?.Invoke() for CL0003

[JaThePlayer]

Previously, these two ways to invoke orig would trigger CL0003, warning about not calling orig on any codepath , even though it is called:

using var detour4 = new Hook(..., static (Action<int> orig, int arg) => {
  orig.Invoke(arg);
});
            
using var detour5 = new Hook(..., static (Action<int> orig, int arg) =>  {
  orig?.Invoke(arg);
});```
