[WebGPU] Abandoned or failed command buffers can workaround some validation
https://bugs.webkit.org/show_bug.cgi?id=286578
rdar://143628699
Reviewed by Cameron McCormack.
We need to check for status == completed prior to assuming the result
in the auxillary buffer contains reliable information.
For instance, a command buffer which was dropped and had a zero ref
count could trigger the completion handler to run without the work
ever being submitted to the MTLCommandQueue.
