feat(audio): Add REV13 audio renderer support

- Implement compressor statistics collection and tracking
- Add explicit splitter volume reset functionality
- Implement REV13 audio device notification commands
- Update feature support system to revision 13
- Maintain backward compatibility with older revisions

Resolves REV13 audio renderer feature requirements with proper
Nintendo Switch development practices and SwitchBrew compatibility.
