CSD: Add possibility to select the BT audio device type

Extended the AdiDeviceState with properties to store the bt audio device
type. As part of the AdiDeviceState these properties will be persisted
with the help of the Secure Settings.

In case a bt device was categorized as headphone/non-headphone device we
send this information to the audioserver which will start/stop the sound
dose computation.

Test: manually changing bt device type
