Expose blockchain APIs in Client

Fix as required and expose in the `Client` all the methods from the
`blockchain` section.

- Fix `gettxout` for `v22`+

.. since then `ScriptPubkey` dropped the `addresses` and `reqSigs`
field (see
https://github.com/bitcoin/bitcoin/blob/master/doc/release-notes/release-notes-22.0.md#new-and-updated-rpcs
and bitcoin/bitcoin#20286).

- Expose `getblockcount` for `v19`+ clients
- Expose `getblockhash` for `v19`+ clients
- Expose `getblockheader` for `v19`+ clients
- Expose `getblockstats` for `v19`+ clients
- Expose `getchaintips` for `v19`+ clients
- Expose `getchaintxstats` for `v19`+ clients
- Expose `getdifficulty` for `v19`+ clients
- Expose `get*mempool*` for `v19`+ clients
- Expose remaining `get*txout*` for `v19`+ clients

.. as they was previously only available in `v17` and `v18`.
