Webgpu: Mesh.setVerticesBuffer doesn't work as I expect it to

Found it! See Mesh.setVerticesBuffer webGPU test | Babylon.js Playground (babylonjs.com)

The problem was the datatype for the index buffer. We should use Uint16Array instead of Uint32Array. No need to use vertexData.applyToMesh(mesh);

Now all the computation is done on the GPU.
@roland by the way, no need to call any dispatch to see the square on the screen
