This will allow further cleanups and optimizations in capture/target/bubble event delivery. For simplicity, ATM every widget will receive its own GtkEventControllerLegacy, it could be desirable to add finer control over this in the future, so widgets that fully use event controllers for input management can do away without this legacy piece.
