test: test mempool rejection in interface_zmq.py

Summary:
Add a test to generate a "R" notification by:

• sending a tx on node0 while the nodes are disconnected
• verifying that this transaction is added to node0's mempool
• generating a conflicting tx on node1
• mining the conflicting tx into a block on node1
• reconnecting the nodes
• checking that the first tx is rejected on node0

Also add noban permission to all nodes to avoid the tx relay delays, because there are a lot of calls to sync_all and this diff adds more of them. This reduces the test run time from 45s to 14s.

This replaces the RBF tests that were in [[https://github.com/bitcoin/bitcoin/pull/19572 | core#19572]] backported in D10306.
