feat: use messaging object to pass message to workers

[edusperoni]

This is still a WIP. It uses a lot of node code to pass messages between the workers. This already allows us to pass 2 things we previously couldn't:

1. SharedArrayBuffer
2. circular objects

this PR will be complete once we're able to pass host objects as well, which will require some additional thought, as we might need to add more logic into the wrappers (like making the objects they hold shared_ptrs), so they can be released only when all are released. Since we're redesigning all our host objects logic for v8 v11.x, we might just delay this implementation
