* 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

-- Removed particle handle pointers from event payloads, as these are unsafe on the GT where they are often utilized.
-- Test proxy pointers when used on the game thread in case the proxy is pending destruction and is no longer valid.
-- Moved transform of particle handle -> transform group index for geometry collection event to PT where it is safe to reference the particle handle.
