   This PR enables one more of the non-wallet functional tests (feature_fee_estimation.py) to be run even with the Bitcoin Core wallet disabled by using the MiniWallet instead, as proposed in #20078. It takes use of the recently introduced methods {create,send}_self_transfer_multi (#24637) which allows to specify multiple UTXOs to be spent rather than only one. Very likely the test can still be simplified (e.g. coin selection in small_txpuzzle_randfee), but this is a first step.

   This test can now be run even with the Bitcoin Core wallet disabled.
