[WebGPU] GPUCanvasContext.configure(Rgba16float) crashes in IOSurface creation
https://bugs.webkit.org/show_bug.cgi?id=269582
<radar://123096556>
Reviewed by Dan Glastonbury.
rgba16float is a supported GPUCanvasContext format according to the
specification,
but HTMLCanvas doesn't support rgba16float yet. So according to the WebGPU
specification,
we are supposed to clamp the luminance to [0,1], leaving the chroma unchanged.
Do so with a custom compute shader.
