No need for blank lines.

This doesn't need to be RefCounted. There will never be an instance of this class.

I think we should follow WebKit style here and use CamelCase. As long as the values are what the IDL exposes, we should be ok.

e.g.

enum class GPUBufferUsage : uint32_t {
  None = 0,
  MapRead = 1,
  MapWrite = 2,
  ...
}

> Source/WebCore/platform/graphics/gpu/cocoa/GPUBufferMetal.mm:48
> +    const char* const functionName = "GPUBuffer::create()";
> +#if LOG_DISABLED
> +    UNUSED_PARAM(functionName);
> +#endif

I suggest just putting this into each LOG statement rather than having a local variable.

Not needed for this test.

> LayoutTests/webgpu/buffers.html:14
> +    assert_true(buffer instanceof WebGPUBuffer, "creatBuffer returned a WebGPUBuffer");

Typo: create.

> LayoutTests/webgpu/buffers.html:23
> +    let floatArray = new Float32Array(arrayBuffer);
> +    assert_equals(floatArray.length, 4);
> +
> +    floatArray[0] = -1;

> +    floatArray[2] = 0;
> +    floatArray[3] = 1;

It turns out that this isn't how you'd use the API, but it's still exercising the things you've built, so we should keep it.
