Windows: Fix false positive detection of new device insertion when clear keys option is enable
When this option is enabled, we first build the list of currently inserted devices then we start listening to insertion events.
When a device insertion occurs, we check if this device is on our list and if yes, we ignore its insertion.
We also ignore devices whose Device ID starts with "SWD\" and "ROOT\" since these are not real devices.
