Implement a PulseAudio audio backend as an alternative to CRAS for Linux desktop environments. This enables crosvm audio output on systems running PulseAudio without requiring ChromeOS audio infrastructure. Key components: - pulse_audio: crosvm device implementing AsyncPlaybackBufferStream with push/pull bridge, connection management with auto-reconnect, and sample format mapping - pulseaudio-rs: Pure Rust PulseAudio protocol implementation (third_party) - seccomp: PulseAudio device policies for sandboxed operation - Configuration options: pulse_socket_path, pulse_cookie_path, pulse_debug_file_output Features audio_pulse feature flag to enable the backend.
