* 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

The Nanite builder now accepts a set of meshes that will be built into a single resource with a hierarchy root for each input mesh.
Updated runtime code to use this feature for Geometry collection.
Each GC now takes up just a single root page.
Changed geometry collection serialization so Nanite data is now transient similar to how it is transient in RenderData for StaticMesh.
Added bogus serialization functions for parsing and throwing away the old Nanite data, so we don't crash when parsing old files.
