[Relay] Dump all ops' outputs: VM or Graph runtime?

One more question: For this PR,does it support BYOC self-defined fused pattern???

In BYOC, customized hardware can define its own fused pattern, however, it won’t make any change to the computation part.

So I am wondering if this graph executor debugger support it. Or, is there any de-fused pass that can revert the customized fusion patterns which also makes sense.
