effects: Use unique device for replaying events to QQuickView

Browse source 
When a new mouse event is made it updates the global position of that
device. This causes issues if a mouse event is forwarded with an
adjusted position then used afterwards.

`QPointingDevice::primaryPointingDevice` creates a new pointer device
internally if the seat name does not exist. It is then shared between
future usages.
