<summary>Changes</summary>
We need to create symbols with "the original shape of resource and element type" to put in the resource metadata in order to generate valid DXIL.
Note that DXC generally doesn't emit an actual symbol outside of library shaders (it emits an undef of a pointer to the type), but since we have to deal with opaque pointers we would need a way to smuggle the type through to match that. Instead, we simply emit symbols for now.
