-- 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

- Added instance data validation
- Added general load balancer for instance processing on GPU (will move to own files later)
- Added initial GPU-side write access API for GPU scene.
- Addded specialized kernel to update primitive IDs in instances when that is the only change.

Pages can now refererence data from the parent page.
Page transcoding is now batched based on page dependencies.
Removed Nanite's LZ container for platforms that don't have hardware LZ. Rely on iostore compression instead. ~4% disk saving. 32mb system memory saving from temp buffer.
Better integer-based UV quantization code similar to new position quantization.
Got rid of remaining old position quantization code.
Reduced float4s per cluster from 8 to 6. ~2% memory density.
Added BitStreamReader support for reading from UAV. Needed to reference parent data.

* 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
