Addition of Network Version 22 skeleton

@Stebalien @fridrik01 do we need to add a nv22-dev feature in cargo.toml have a #[cfg(feature = "nv22-dev")] for creating new fvm?

[fridrik01]

Accepting as long as test failures are addressed before merging.

EDIT: Also added some additional comments since I reviewed this originally quite late

Could you please advise on this? (I noticed we do this in previous ones, assuming it’s for avoiding unintended potential consensus breaking change?

I don't know if its strictly necessary but given that @Stebalien is out, then it would be the safe option here, so I would vote yes.

We also need to add nv22-dev as a feature in fvm/Cargo.toml (see here for example)

One last nit, but LGTM with that.
