Returns the byte size of the GPU shader function.
This can be helpful if the application wishes to tally up memory usage.

This function returns the handle to the Hgi backend's gpu resource, cast to a uint64_t.
Clients should avoid using this function and instead use Hgi base classes so that client code works with any Hgi platform. For transitioning code to Hgi, it can however we useful to directly access a platform's internal resource handles. There is no safety provided in using this. If you by accident pass a HgiMetal resource into an OpenGL call, bad things may happen. In OpenGL this returns the GLuint resource name. In Metal this returns the id<MTLFunction> as uint64_t. In Vulkan this returns the VkShaderModule as uint64_t. In DX12 this returns the ID3D12Resource pointer as uint64_t.
