[PATCH v4 3/5] winebth.sys: Implement IOCTL_WINEBTH_AUTH_REGISTER.

[Vibhav Pant]

From: Vibhav Pant

This requests the system's Bluetooth service to send all incoming authentication requests to Wine's
auth agent. This may be necessary to receive requests if another pairing agent outside Wine is
already running.
