This introduces a new API on `ESCInputsManager` that makes it possible to inject custom logic for processing input events. An example of how to use this API will be introduced in a separate commit as part of https://github.com/godot-escoria/escoria-demo-game/pull/503 via a new plugin, `addons/escoria-ui-keyboard-9verbs/`, which shows how this can be used to add support for keyboard shortcuts to select a specific verb.
