WebGPU:

Indicates the value to clear GPURenderPassColorAttachment#view to prior to executing the render pass. If not map/exist|provided, defaults to {r: 0, g: 0, b: 0, a: 0}. Ignored if GPURenderPassColorAttachment#loadOp is not GPULoadOp#"clear". The components of GPURenderPassColorAttachment#clearValue are all double values. They are converted [$to a texel value of texture format$] matching the render attachment. If conversion fails, a validation error is generated.
