Cannot create WGPUInstance

[Ravbug]

The generated function for _wgpuCreateInstance is not complete:

function _wgpuCreateInstance() {
 abort("TODO: wgpuCreateInstance unimplemented");
}

However, other functions (like _wgpuInstanceRequestAdapter) are implemented. Is it possible to use WebGPU with Emscripten?

Version of emscripten/emsdk:
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.38 (9eff02bc816c50ab0e3b70a3bd5b72a8dc2893a2)

I believe at least this test is known to pass:

emscripten/test/webgpu_basic_rendering.cpp

Line 4 in 9677b7d

// found in the LICENSE file.

@kainino0x would know more.

Use a nullptr instance, as in the tests and this sample: https://github.com/kainino0x/webgpu-cross-platform-demo

    // Left as null (until supported in Emscripten)
    static const WGPUInstance instance = nullptr;
