Upcoming implementations of the streams of the primary module will need to change the underlying stream type depending on the current connected device. The stream context must persist, thus its life time must be bound to the IStreamIn/Out implementation. Move the StreamContext instance under ownership of StreamIn/Out. Add StreamCommonImpl::onClose so that the owner of the context may know when it is safe to reset it. Re-arrange the order of the arguments when creating a stream so that the context always comes first. Bug: 264712385 Test: atest VtsHalAudioCoreTargetTest Change-Id: Iaf13d4bc3a53cbfc27264d3abd1f6c417ece3941
