Perf(HookDevice): Disable shader constant tracking
Perf(HookDevice): Disable shader constant tracking

- In a simple scene this used 10% of a thread in _checkShaderConstants, plus a bit more in various stl::map things.  Turning it off didn't help FPS much in that case, but could become excessive if there are a lot of animations happening or other render effects that require constant swapping.  Since its unused anyway, commenting it out for now.  Hopefully, if needed for shader modding, can get by with only using it in snapshot mode.
