Add skeleton for nv23 to support development and testing

[rjan90]

With the development/testing and shipping of nv22 coming to an end, we need to add the skeleton for nv23 without any upgrade epochs, code / state changes / migrations. It should have no effect except on local devnets to unblock implementation work, testing and tests.

How to create this skeleton is documented in: https://github.com/filecoin-project/lotus/pull/11065/files (which we probably should merge now, and iterate on rather then it staying in a PR).

In Progress:

Filecoin-FFI: filecoin-project/filecoin-ffi#454
Go-State-Types: filecoin-project/go-state-types#257 and filecoin-project/go-state-types#258
Lotus: #11897

Ran the nv23 skeleton with the above mentioned PRs locally, and had a successful pre-migration, migration and network upgrade:
