The intangible type is currently implemented as size-less type, but that might change as the HLSL implementation evolves. Setting the width to 0 here matches what similar types from other languages have done, for example `__externref_t` in WebAssembly, which is also an opaque type whose value cannot be accessed or manipulated, only passed around.
