[WebGPU] GPUCommandEncoder.clearBuffer does not appear to work.

Apply the following patch to instanced-textured-cube.js:

diff --git a/Websites/webkit.org/demos/webgpu/scripts/instanced-textured-cube.js b/Websites/webkit.org/demos/webgpu/scripts/instanced-textured-cube.js

         /* GPURenderPassEncoder */
         const renderPassEncoder = commandEncoder.beginRenderPass(renderPassDescriptor);


it still seems to work as usual with an occasional flash. Which means the clear isn't happening in general or consistently.
