Geoffrey McRae d23a7a3cf2 [idd] helper: release authority during device removal ...

Register the retained LGIdd authority handle for service device
notifications. Close the exact handle before granting query-remove.

Use cancellable overlapped control requests so the SCM handler never
waits for driver I/O while Plug and Play is removing the device.

Keep authority publication, host liveness, and child activation under
one synchronized state machine to prevent activation after removal.

Retire device notifications on the service thread and keep polling for
the interface so a manual re-enable recovers without a service restart.
