This makes a nearly one-to-one mapping between the JS and C APIs, which benefits projects like Blink and Emscripten. - JavaScript's `undefined` is equivalent to C `WGPU_STRIDE_UNDEFINED`. - JavaScript's `0` is equivalent to C `0`. - To implement the API correctly, Blink must special-case an actual value coming in from JS that is equal to WGPU_STRIDE_UNDEFINED (0xFFFF'FFFF), and inject an error. Keeps but deprecates a reasonable approximation of the old behavior.
