This commit addresses serveral bugs within the audio service where OpenAL would fail to register the output device to the mapped engine.
- Increase null safety checks for all audio backends (cubeb, sdl2, openal)
- Added failsafe for Device selection
These ensure the audio_renderer can validate calls from the OpenAL engine, Credits to Hayate Yoshida for helping Identify the issue.

- Add complete OpenAL sink implementation with robust error handling
- Support for device enumeration using ALC extensions
- Implement dummy streams for graceful degradation when OpenAL fails
- Add proper audio threading and buffer management
- Include comprehensive logging and diagnostic information
- Add stream limits and retry mechanisms for stability
Additional changes:
- Add ENABLE_OPENAL CMake option and OpenAL dependency management
- Include openal-soft in vcpkg dependencies
- Add OpenAL to audio engine settings enum
The OpenAL backend provides an alternative audio solution alongside
existing Cubeb and SDL2 backends, with enhanced device compatibility
and improved error recovery mechanisms.
