Line-of-Sight audio Occlusion and Obstruction

[phevosccp]

Description

This PR implements basic occlusion/obstruction using LPF and implementing SetObjectObstructionAndOcclusion() from the Wwise API.

In addition to that it manages emitterIDs that are occluded/passthrough and handle fade in/out internals.
This implementation differs from the Acoustics API in the sense that it completely relies on Carbon's (destiny) line-of-sight ray tracing checks to know what is occluded and what not.

The whole path end to end in short is the following: Destiny → Python → trinity → CarbonAudio → Wwise.

Technical details:

• New class AudObstructionOcclusion : Owns all per emitter obstruction/occlusion and talks to the wwise API. We store the emitter IDs and states in a unordered map and handle their states, in addition we also handle fade/in out intervals
• The class has no concept of the actual emitter states so it reads that from AudManager
• It's also important to note that currently we disable basic occlusion/obstruction when acoustics are ON to avoid attenuation stacking (e.g -12dB occlusion + -12 dB tranmission = -24dB reduction which is unexpected ). This will potentially change with the introduction of trigger volumes and we will keep both systems alive.

Lifecycle

• Update loop : AudManager::Process(), once per tick, before RenderAudio()): advances all fades using a clock delta and sends only changed values to Wwise.
• Emitter validation : values are only accepted/tracked for emitters that actually exist, see WithCallbackGameObject
• Culling : emitters that are currently culled are skipped but keep fading
• Cleanup : entries that fade fully back to unblocked are dropped to keep the map small , see UnregisterGameObject()

Testing

Tested and implemented for EVE Frontier.
