Merge #20126: test: p2p_leak_tx.py improvements (use MiniWallet, add p2p_lock acquires)

Browse Source 
5b77f8098de537898151ab116d0e547fd6ff9466 test: add p2p_lock acquires in p2p_leak_tx.py (Sebastian Falbesoner)
cc8c6823b4a8b74922f78ce6ce527ced9325bd49 test: use MiniWallet for p2p_leak_tx.py (Sebastian Falbesoner)

Pull request description:

  This PR enables one more of the non-wallet functional tests (p2p_leak_tx.py) to be run even with the Bitcoin Core wallet disabled by using the new MiniWallet instead, as proposed in #20078. It also adds missing p2p_lock acquires that need to be held while modifying internal p2p Interface state (in this case the `last_message` dictionary) to avoid data races.
