a07910abcd test: Makes wtxidrelay support a generic P2PInterface option (Antoine Riard)
Pull request description:
This is a simple functional test to increase coverage of #19988, checking that txid announcements from txid-relay peers are delayed by TXID_RELAY_DELAY, assuming we have at least another wtxid-relay peer.
