Merge #20171: Add functional test test_txid_inv_delay

bc4a230087 Remove redundant p2p lock tacking for tx download functional tests (Antoine Riard)
d3b5eac9a9 Add mutation for functional test test_preferred_inv (Antoine Riard)
06efb3163c Add functional test test_txid_inv_delay (Antoine Riard)
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.

  You can verify new test with the following diff :
