Lazy-load audio engine

[Kryptos-FR]

Is your feature request related to a problem? Please describe.
The audio providers/components/etc. are always initialized in a game, even if all scenes don't have any audio component/listener.

Describe the solution you'd like
Have the audio system initialize on-demand (when it is first needed).

Describe alternatives you've considered
This behavior could be driven by a configuration option, where audio is

• opt-out: in which case any attempt to initialize it would throw
• lazy-load: initialized on first use
• pre-load (current behavior): initialized at the start

Additional context
While rare, some games might not need any audio. Not initializing that part of the engine might save some memory and improve performance.

Another use case is when trying to run a game from WSL where audio is not supported by default. Granted, it is niche but very useful for developers to quickly test whether a game works correctly on Linux without requiring dual-boot or another machine.

Also, just when learning game phycics and gaming logic and concepts, one doesn't need necessarily audio.

Could an EntityProcessor be the solution for this?

Have a component for audio and when its added use the OnSystemAdd from the processor to initialize the audio provider.
