🧹 Remove Fork() and Swap()

[greymistcube]

We can finally assume forking and swapping of chains would not happen through normal operations. 🙃
As such, once 5.3.0 is released, we can perform an analysis on an IStore and migrate/prune the internal DB and simplify the IStore interface accordingly.

Here, in NineChronicles.Snapshot use a fork and swap afaik. Could you check it?

I have checked it. It is all done externally without using BlockChain.Fork() or BlockChain.Swap().
Although, I have been thinking maybe we should provide a tool to manipulate IStore and IStateStore more safely. 🙄
