Original CL Desc
-----------------------------------------------------------------
Memory optimizations for Recast (Detour). I used UE_LOG in recast as it's already there. Also I only added [at]UE BEGIN [at]UE END for the big stuff as a hint that its been changed in case of issues.

- Deprecated enum EActorGridPlacement and replaced AActor::GridPlacement by bIsSpatiallyLoaded.
- It makes more sense from a user perspective to set an actor as "non-spatially loaded" instead of "always loaded", especially with data layers.
- If we ever need it, having the possibility to set actors to use their location or bounds to go in the grid will be a per-grid setting.

1. Nanite meshes are not longer marked as always visible, and will go through the standard rendering culling / pipeline.
2. Add coarse frustum culling using the already existing scene octree.
3. Remove Distance visibility bit array, and converted only usage to using the visibiliity map. (Spoke with Kenzo about this, the original was put in due to differences between distance a vis flags, but this has been fixed)
4. Optimized Frustum culling methods across the board.

- usable to understand (per navmesh) how many tiles we are dirtying and what the biggest offenders are

Added a new weakptr "OptionalSourceObject" in the FNavigationDirtyArea, needed to support the previous change

In some code paths for loaded actors the call order might be different since primitive registration gets deferred (i.e. FRegisterComponentContext != nullptr).
Case 1 (normal flow): FRegisterComponentContext == nullptr
> UPrimitiveComponent::CreateRenderState_Concurrent : calls CreateSceneProxy
> RegisterDebugDrawDelegate
> UnregisterDebugDrawDelegate ==> works fine
Case 2 (deferred AddPrimitive): FRegisterComponentContext != nullptr
> UPrimitiveComponent::CreateRenderState_Concurrent : defers CreateSceneProxy
> RegisterDebugDrawDelegate (skip register since not init)
> CreateSceneProxy
> UnregisterDebugDrawDelegate ==> ensures in UnregisterDebugDrawDelegate
With this new version `CreateRenderState_Concurrent` calls `RequestRegisterDebugDrawDelegate` that will take care of registering the delegate immediately or mark it for deferred execution. An explicit call to `ProcessDeferredRegister` is then required from `CreateSceneProxy` to implement proper flow:
Case 2 (fixed) (deferred AddPrimitive + deferred Register): FRegisterComponentContext != nullptr
> UPrimitiveComponent::CreateRenderState_Concurrent: defers CreateSceneProxy
> RequestRegisterDebugDrawDelegate: defers RegisterDebugDrawDelegate
> CreateSceneProxy: calls ProcessDeferredRegister & RegisterDebugDrawDelegate
> UnregisterDebugDrawDelegate ==> works fine
Bonus:
- New DebugDrawComponent abstract class that is now used to share common functionalities between existing debug related components. Takes care of DelegateHelper registration flow to render text on screen from different sources.
- FDebugDrawDelegateHelper::InitDelegateHelper is no longer virtual and derived classes requiring extra data from their associated scene proxy should set it up from their overriden CreateSceneProxy
- FDebugDrawDelegateHelper derived classes should not override RegisterDebugDrawDelegate/UnregisterDebugDrawDelegate to use their `DrawDebugLabels` method since this is already a virtual method that would get called from the base class.
- Fixed a few ViewFlag members in the SceneProxy so the DelegateHelper base class can behave as expected

That change was made to help with a user experience issue but it's causing more issues than benefit.
