The following patches expose AdvertisingDataFlags in Device API.
This is need by Android app on ChromeOS as Android normally
get Advertising data flag from Bluetooth adapter.

I prefer if we just call this AdvertisingFlags and strictly speaking this needs to be array{uint8}. The AD type is defined as variable length. It is not just an uint8. We could debate to go with uint32 here if that helps, but just a uint8 will lock us in and is not really future proof.
Regards
Marcel

This adds 'AdvertisingDataFlags' property to Device interface.
Bluetooth Core Supplementary Spec v6 Chapter 1.3 defines Bluetooth
Flags as one of the data in advertise data. BlueZ also correctly
parses this data but never exposes it to upper layer.
