Support configuring AVSession

[simlay]

Seems like iOS 17+ requires configuring an AVSession with an AVAudioSessionCategoryPlayback

(Possibly) Related issues:

• iOS randomly chooses speaker and earpiece cpal#862
• CoreAudio on iOS lists no input devices cpal#842
• stops all playing audio on ios NiklasEi/bevy_kira_audio#118

It's unclear if a fix should go in coreaudio-rs or in coreaudio-sys.
