Pull request description:

  ## Additional Information

  * [bitcoin#19572](https://github.com/bitcoin/bitcoin/pull/19572) introduces tests in `interface_zmq.py` that validate newly introduced "sequence" reporting of all message types (`C`, `D`, `R` and `A`). The `R` message type (removed from mempool) is tested by leveraging the RBF mechanism, which isn't present in Dash.

    In order to allow the tests to successfully pass, all fee bumping and RBF-specific code had to be removed from the tests. This test also involves creating a new block to test the `C` message (connected block) that would return a `time-too-new` error and fail unless mocktime has been disabled (which has been done in this test).

  * When backporting [bitcoin#18309](https://github.com/bitcoin/bitcoin/pull/18309) ([dash#5728](https://github.com/dashpay/dash/pull/5728)), Dash-specific ZMQ notifications did not have those changes applied to them and that particular backport was merged upstream *after* [bitcoin#19572](https://github.com/bitcoin/bitcoin/pull/19572), meaning, for completion, the changes from [bitcoin#18309](https://github.com/bitcoin/bitcoin/pull/18309) have been integrated into [bitcoin#19572](https://github.com/bitcoin/bitcoin/pull/19572)'s backport.

    As for the Dash-specific notifications, they have been covered to ensure uniformity in a separate commit.

  * The ZMQ notification interface has been converted to a smart pointer in the interest of safety (this change is eventually done upstream in 8ed4ff8e05d61a8e954d72cebdc2e1d1ab24fb84 ([bitcoin#27125](https://github.com/bitcoin/bitcoin/pull/27125)))

Internal c++ interfaces

The following interfaces are defined here:

  • Chain — used by wallet to access blockchain and mempool state. Added in #14437, #14711, #15288, and #10973.

  • ChainClient — used by node to start & stop Chain clients. Added in #14437.

  • Node — used by GUI to start & stop bitcoin node. Added in #10244.

  • Wallet — used by GUI to access wallets. Added in #10244.

  • Handler — returned by handleEvent methods on interfaces above and used to manage lifetimes of event handlers.

  • Init — used by multiprocess code to access interfaces above on startup. Added in #6143.

  • Ipc — used by multiprocess code to access Init interface across processes. Added in #6143.

The interfaces above define boundaries between major components of bitcoin code (node, wallet, and gui), making it possible for them to run in different processes, and be tested, developed, and understood independently. These interfaces are not currently designed to be stable or to be used externally.
