-- Removed per observed controls for StartMode, CacheMode and moved to a single set of controls on the cache manager.
-- Cache takes name from observed component.
-- Placed CacheCollection automatically set to Kinematic, non-placed are Record
-- Random access start frame
-- Consistenty record all transforms in Actor space
-- Compatible with Sequencer control
-- Created Playback only CacheManager subclass
-- GeometryCollection recording abides component flags to record/playback breaking/collision/trailing events

[CL 16684502 by brett miller in ue5-main branch]
* Moved Nanite resource ID and hierarchy offset back to primitive data (indirection cost is largely noise these days, and memory savings is more important - GetInstanceData() fetches this data and stores in the pre-existing registers so all the callsites don't have to worry about it).
* Removed FNaniteInfo from FPrimitiveInfo (and the type itself) in favor of just having a 32bit per-instance hierarchy root offset. Hierarchy offset and runtime resource ID just sourced from primitive.
* Removed PrimitiveID from CPU instance data (GPU still needs it). This value was redundantly stored per-instance, and now the GPU Scene upload just blits it over from primitive when the instance data is uploaded.
* Added new virtual GetNaniteResourceInfo on FPrimitiveSceneProxy that retrieves the Nanite resource ID and hierarchy offset stored on a given primitive (needed now that FPrimitiveInstance doesn't cache a copy). The non-virtual FPrimitiveSceneProxy::IsNaniteMesh() helper is used to avoid this virtual function call for non-Nanite proxies.
* Removed deprecated and no longer referenced Nanite::FResources array on FNaniteGeometryCollectionSceneProxy
* Removed expensive per-instance checks() in a few spots
* Stubbed out upcoming per instance payload allocator offset
* Removed deprecated and never referenced non-GPUScene GetInstanceData uniform buffer path
* Significantly cleaned up and optimized a lot of ISM instance data retrieval, including avoiding unnecessary FRenderTransform <-> FMatrix conversions.
* Removed GetInstanceShaderValues API, it was inefficient and annoying to require retrieval of all parameters when often only one or two of them were ever used. In some cases even the origin was unused but .w was needed because of the per-instance random packing.
* Implemented explicit GetInstanceRandomID() accessor to fetch (under current packing) Origin.W without exposing this to the callsites
* Implemented public API for GetInstanceLightMapData(), since the internal version was only accessible by GetInstanceShaderValues()
* Renamed GetInstanceShaderCustomDataValues() -> GetInstanceCustomDataValues() for API consistency

* Implemented thread safe object pool / free list allocator (FGeometryCollectionDynamicDataPool)
* Added Chaos stats for total transforms and changed transforms
* Removed TransformsAreEqual mechanism that caused full transform updates to occur unnecessarily for 2 subsequent frames, as the state wasn't stable until the previous 3 frames were stable. This was incredibly innefficient for GPUScene, etc..
* InitDynamicData now returns the data allocation (which can be null if not dynamic or if no transforms have changed), users of this now check if it's available, and either skip or fall back to the static/rest path otherwise
* Cleaned up some code paths by combining them with similar passes
* Removed tons of allocations, including heavy allocations/memcopies of transform data, even on stable frames (which were immediately deallocated right after allocation and setup of the dynamic data)
* Saves ~0.5 to 1.0ms of CPU time in heavy scenes
* Saves ~0.5ms of GPU time doing far less GPUScene updates
* Main optimization around this refactor is forthcoming in a followup CL (avoid calling MarkRenderTransformDirty in TickComponent).

-- Changed how particle to proxy mapping is implemented. Removed the map maintained on the solver. Each particle now maintains its own pointer to the associated proxy. Internal cluster particles are linked to multiple proxies (necessarily: they need this information to mark proxies dirty during the buffering process). Internal cluster particles have a set of proxy pointers that are used in situations that require it.
