WebGPU code refresh needed: layout parameter now required in createRenderPipeline calls

[tidoust]

The WebGPU specification (and implementation in Chrome) has evolved slightly since the samples were written. The layout parameter is now required when calling createRenderPipeline or createComputePipeline. Adding layout: 'auto' in calls to createRenderPipeline could be enough to fix that part (unless the code uses a more specific pipeline).

(That said, I think that some of the constructs in WGSL need updating too. I haven't tried to dig into that.)

since chrome 114 there is more issues with this sample.
I refactored code to make this sample working with newest chrome releases.
Sadly i can't open PR here, so i'm attaching path if anyone interested
