This makes all the regular WebGPU object creation handle errors properly in the Vulkan backend instead of ASSERTing no Vulkan error is raised. Static Create functions are added to all these types so that the details of how the initialization is done is private, and it isn't possible to construct an object but forget to initialize it.
