fix: sync: atomically switch chains when checkpointing (#11595) 
We can now atomically switch chains when checkpointing. Previously,
we'd call `SetHead` followed by `SetCheckpoint`. Unfortunately, that's
not atomic and the "head" could have reverted before we called
`SetCheckpoint` (causing the latter to fail).

Now, we just call `SetCheckpoint` and let `SetCheckpoint` adjust our
head. This changes the behavior of `ChainStore.SetCheckpoint`, but
`Syncer.SyncCheckpoint` is the only caller anyways.

8f309b214b chain: move checkpoint logic into chainstore 
That way, checkpoints can be enforced by the chainstore, removing a
potential race where an in-progress sync of a fork could bypass a sync
checkpoint.

69da6a2a29 feat: allow checkpointing to forks 
Previously, `lotus sync checkpoint` would only checkpoint on the current
chain. Now, it can switch to a new fork.
