Bluetooth: HCI: Fix not always setting Scan Response/Advertising Data
The scan response and advertising data needs to be tracked on a per
instance (adv_info) since when these instaces are removed so are their
data, to fix that new flags are introduced which is used to mark when
the data changes and then checked to confirm when the data needs to be
synced with the controller.
