bluetooth: Add AudioSession/Control methods for AIDL track metadata

Add overloads for UpdateSink/SourceMetadata that
accept android.hardware.audio.common.Sink/SourceMetadata types.
Move include of hardware/audio.h to BluetoothAudioSession.cpp.
This allows to use this code from "pure AIDL" modules.
