Merge bitcoin/bitcoin#23558: test: run rpc-generateblock.py even with wallet disabled

1e86ff7 test: run rpc-generateblock.py even with wallet disabled (Darius Parvin)

Pull request description:

  Run rpc_generateblock.py test even when the wallet is disabled, as discussed in #20078.

  This PR picked up from where #20808 left off, started by @ nginocchio. Since then, there have been many improvements to `MiniWallet`, making this PR more straightforward.

  L23 makes use of `MiniWallet.rescan_utxos()` to add the pre-mined block utxos (when `self.setup_clean_chain` is not set to `True`), rather than generating new blocks during the test.
