hle/service/audio: Implement missing audio services and functions

- Add complete IAudioController implementation with 32 missing functions:
  * Volume control (GetTargetVolume, SetTargetVolume, etc.)
  * Mute control (IsTargetMute, SetTargetMute, etc.)
  * Target management (SetDefaultTarget, GetDefaultTarget, etc.)
  * Play report functions (10000+ series command IDs)
  * Hearing protection safeguard functions
  * Debug and system functions

- Add new audio services:
  * codecctl - Codec controller service with 13 functions
  * auddebug - Audio debug service placeholder
  * Device suspend/resume services (audout:d, audin:d, audrec:d, audren:d)
  * System audio services (aud:a, aud:d)
  * Applet audio services (audout:a, audin:a, audren:a)

- Update IAudioDevice with missing functions:
  * GetAudioSystemMasterVolumeSetting
  * GetActiveAudioOutputDeviceName
  * Fix function ID mappings to match official documentation

- Register all services in main audio LoopProcess function
- Update CMakeLists.txt with new source files

All implementations follow the official Switch audio services documentation
from switchbrew.org and provide appropriate stub implementations with
sensible default values for enhanced game compatibility.
