WebGPU: Should reject with an OperationError if GPUDevice is lost

The popErrorScope() was changed to reject with an OperationError if the
GPUDevice is lost[1]. So, this patch matches up with the spec. Also,
although the spec doesn't mention it yet, we should make it throw an
OperationError for all cases where the device is lost.
