graham wihlidal 32e893af72 Fix for race condition where GCs might reach the call to RequestGPUSceneUpdate() on initial proxy creation before the primitive scene info has a valid index (entry in GPU Scene bookkeeping), causing the updates to silently skip. Normally this problem doesn't affect the majority of GCs, since most GCs have identify transforms in rest pose, except some GCs authored in external DCC tools could use non-identify transforms that wouldn't be correctly uploaded to GPUScene until simulation would start. Also took the time to remove the virtual function calls on IsNaniteMesh() and IsAlwaysVisible() since these are called super heavily in frustum culling and init views on the CPU. ...
