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<MTLSamplerState> as uint64_t. In Vulkan this returns the VkSampler as uint64_t.

Implements HgiSampler.
