dix: Use DeliverGrabbedEvent for implicit passive grabs (#25400)
A client requesting a GrabModeSync button grab, owner-events true, with only the ButtonRelease mask set would never receive the press event even if the grab window had the ButtonPress mask set. The protocol requires that if owner-events is true, then the delivery mask is the combination of the grab mask + the window event mask. DeliverGrabbedEvents does this already for us, checking first the delivery based on owner_events and then based on the grab mask. AFAICT, the device cannot enter the states FREEZE_BOTH_NEXT_EVENT or FREEZE_NEXT_EVENT that would be handled by DGE in any possible path here. Bonus point - CheckPassiveGrabsOnWindows suddenly becomes a lot lesss complicated.
