feature: Add Rive Event bindings to iOS runtime
Adds event bindings for iOS/macOS **Caveat:** tl;dr We may have to explicitly make app owners open URLs for `OpenUrlEvent`, rather than doing it implicitly Recently, there was a [request for a specific change](#267) to mark `RiveRuntime` package as using application-extension-safe in terms of API usge. This allows RiveRuntime to be used in places other than apps in the Apple ecosystem, which they needed, so that Apple doesn't flag their apps negatively in App Store submissions. Because we mark this setting in build settings for our package, this means we can't use a specific API to access `UIApplication`, which is needed to open URLs from our side (i.e. `UIApplication.shared.open(url)`), thus not allowing us to _directly_ open URLs on `OpenUrlEvent`. Couldn't find a way around this unfortunately, so the onus on opening the URL will be on the consumer when they listen for this event.
