Minor - Adds FMOD integration for audio support - V13.4.0

Initializes FMOD sound system within the application class and propagates it to the entity manager and entities. This allows for audio components to access and use the FMOD system for playing sounds.

Removes redundant FMOD system initialization from the audio component.
