Subject: [PATCH] bitcoin-gui: Implement missing Init::makeMining method

A missing Init::makeMining implementation was causing internal code using the
mining interface (like the `waitforblockheight` RPC method) to not work when
running inside the `bitcoin-gui` binary. It was working the other bitcoin
binaries ('bitocind`, `bitcoin-qt`, and `bitcoin-node`) because they
implmemented `Init::makeMining` methods in commit
8ecb6816781c7c7f423b501cbb2de3abd7250119 from #30200, but the `bitcoin-gui`
init class was forgotten in that change.

This bug was reported by Matthew Zipkin <pinheadmz@gmail.com>
