libaudiohal@aidl: Implement setConnectedState

Implement the following methods in DeviceHalAidl:
 - getAudioPort (both overloads)
 - setAudioPortConfig
 - setConnectedState

Add DeviceHalInterface::setSimulateDeviceConnections.
This method only works for the AIDL HAL and allows
testing external device connections in unit tests.
Plumb setSimulateDeviceConnections via the audio
framework to expose to libaudioclient tests.

Make conversions to/from AudioDevice and legacy
to use a corresponding variant for the address.
Fix invalid addresses in audiopolicy_tests.
