Expose `BlockLocator`

[dahlia]

It will be great if we can remove this and make Libplanet internals used in Libplanet.Net public.

Currently Libplanet allows Libplanet.Net to see its internals in order to keep BlockLocator internal. However, it would be better if it is exposed as a public class instead.

This issue is extreamly easy.

The goal of this issue is not to focus on understanding the structure of libplanet, but rather to follow the process of contributing to libplanet. We are looking forward to familiarizing you with the changelog or lint.

Is the objective of this issue simply making the class BlockLocator public, or removing the lines:

[assembly: InternalsVisibleTo("Libplanet.Net")]
[assembly: InternalsVisibleTo("Libplanet.Net.Tests")]

?

I'm asking because if it's the former it would be really simple, but in case of the latter, the members of the class BlockChain Swap(other, render, stateCompleters), TipChanged, Store, Append(block, evaluateActions, renderBlocks), FindNextHashes(locator, stop, count), Fork(point, inheritRenderers, GetBlockLocator(threshold), IterateBlockHashes(offset, limit) must also be made public, and the code must be swapped around due to the fact that public members should precede the internal members. I wasn't so sure if this is what you would have wanted.

Baby steps. 🙂

As the original https://github.com/planetarium/libplanet/pull/1760#discussion_r792261018 suggest, the goal is eventually to decouple Libpanet and Libplanet.Net, but doing so in one go would be rather hard as you've mentioned.

For now, I think just making partially mentioned entities public and moving around some chunks to pass code analysis would be fine. 😗
