audio: Refactor configuration population

In 'Module::setAudioPortConfig' allow subclasses to provide
their own suggested configuration.

In 'Module::populateConnectedDevicePort' provide the ID of
the device port instance that will be created as a result
of connecting an external device.

Also, expose 'ModuleDebug' flags to subclasses so that they
can know when device connections are simulated.
