core/stateless: add vmwitnessstats cli flag to report leaf stats + log to console (#32619) 
The format that is currently reported by the chain isn't very useful, as
it gives an average for ALL the nodes, and not only the leaves, which
skews the results.

Also, until now there was no way to activate the reporting of errors.

We also decided that metrics weren't the right tool to report this data,
so we decided to dump it to the console if the flag is enabled. A better
system should be built, but for now, printing to the logs does the job.
