Setup mocking panic handling in vm

[austinabell]

Summary of changes
Changes introduced in this pull request:

• In go implementation, they catch any unexpected panic and wrap it with an exit code. We cannot match this (at least currently, but design might be flawed to allow us to safely do) so we just need to handle errors whenever assertions are expected to happen.
  • I've used the added function for the functions I know can and are hit, but there might be others. Until we find a way to match catching panics with other functionality maintained or they change the protocol we will have this vulnerability to our node crashing if anything in actors has a bug

I'll create an issue to detail the issue with actual panic catching. Syncs past 13154 point now
