This MR adds support for getting a Bluetooth adapter's properties from its corresponding `org.bluez.Adapter1` object, and making them available to userspace via device properties and the `IOCTL_BTH_GET_LOCAL_INFO` ioctl, updating these properties whenever a `PropertiesChanged` signal is received for the adapter.
It also adds code for creating and removing radio PDOs on receiving `InterafacesAdded` and `InterfacesRemoved` signals from BlueZ, respectively.
