Pull request description:

  This is another Pr in the series PRs for Coinstatsindex (see overview in #18000). This PR adds the `hash_type` option `muhash` to `gettxoutsetinfo` through which the user can calculate the serialized muhash of the utxo set. This PR does not use the index yet.

    Code review ACK e987ae5a55. Looks very good. I left one suggestion to simplify code, but feel free to ignore it here and maybe consider it for later since PR has already had a lot of review.
