The GPUCommandBuffer interface of the WebGPU API represents a pre-recorded list of GPU commands that can be submitted to a GPUQueue for execution.
A GPUCommandBuffer is created via the GPUCommandEncoder.finish() method; the GPU commands recorded within are submitted for execution by passing the GPUCommandBuffer into the parameter of a GPUQueue.submit() call.
Note: Once a GPUCommandBuffer object has been submitted, it cannot be used again.
