This PR is a follow up to #18216, and re-applies much of the same logic and also keeps consistency with that PR's summary. After a bunch of internal discussions, we decided we want to go ahead with this change and bring it into the modern event system.

The main difference is that now we have a proper fork of the different event systems, we don't need to apply the gated logic around a bunch of places (other than the SyntheticEvent module). I also had to fork a bunch of tests that expect persistance when we run the modern event system. Once we remove the feature flags, we can tidy up a load of code relating to pooling (by removing it all).
