* Rename IsNaniteEnabled to UseNanite and moved to RenderUtils (so it can be used in Components)
* Make proxy creation respect Scene platform level & consistent with renderer using UseNanite function
* Move DoesPlatformSupportNanite to RenderUtils (so it can be used in UseNanite)
* Fix crash in FMobileSceneRenderer::RenderHitProxies from dummy Nanite raster results
* Make ShadowSetup respect UseNanite to avoid creating virtual shadow maps when these are not supported
