cli: move jj bench commands to new module, hide behind feature flag

Browse source 
The `jj bench` commands are mostly meant for developers, so lets hide
the command from help and behind a `bench` feature flag. The feature
flags avoids bloating the binary with the `criterion` dependencies,
which was the reason I removed the command in 18c0b97d9d.
