Makes the following improvements to the listener instructions to make them slightly smaller and more memory-efficient. 1. Removes the default value from the `useCapture` parameter since it generates more code than just castint to `false`. 2. Removes the `useCapture` and `eventTargetResolver` parameters from `ɵɵsyntheticHostListener` since they won't be generated by the compiler, as far as I can tell. 3. Makes it so that we don't have to return a target name from a `GlobalTargetResolver`. This allows us to save on some memory, because we can return a reference to the target without having to wrap it in an object literal. DEPRECATIONS: `EventManagerPlugin.getGlobalEventTarget` is now deprecated and won't be called from Ivy code anymore. Global events will go through `addEventListener`. PR Close #41807
