Integrate Built-in Actor Logs into Lotus Logging System about lotus

[Stebalien]

Logging from the builtin actors means executing messages a second time with logging enabled (ignoring gas limits, I guess?). IMO, we should add some API endpoints like ComputeStateWithLogging, etc.

Alternatively, we can focus on making it easier to extract test vectors for messages and tipsets. E.g.:

lotus state extract-vector <message-cid | message-params | tipset>

Basically, it would be nice to be able to execute an existing message and/or a new message and/or an entire tipset and easily extract a test vector that we can play with in the fvm testbench.

From the sync discussion about this I learned about the tvx tool in the lotus repo. It probably needs some work to bring it up to scratch, and ideally this is the kind of thing you could extract to run in fvm_workbench.
