Minor - Adds audio component with spatialization - V13.3.0

Adds a new audio component with support for loading, playing, pausing, stopping, and controlling audio properties such as volume, pan, pitch, and looping.

Implements spatialization using FMOD, enabling 3D audio effects based on object and camera positions. Includes file selection dialog and UI controls for audio properties.
