areActivitiesEnabled still crashes on some devices

same issue with: https://github.com/istornz/flutter_live_activities/issues/84#issue-2332999443

This issue is because iOS under than 16.1 and Mac doesn't support the method: ActivityAuthorizationInfo().areActivitiesEnabled

So it crashes here:

public class SwiftLiveActivitiesPlugin: NSObject, FlutterPlugin, FlutterStreamHandler {
 ...
 public func handle(_ call: FlutterMethodCall, result: @escaping FlutterResult) {
    if (call.method == "areActivitiesEnabled") {
      if #available(iOS 16.1, *) {
        result(ActivityAuthorizationInfo().areActivitiesEnabled)
      } else {
        result(false)
      }
      return
    }
    ...
    }
...
}

ActivityAuthorizationInfo().areActivitiesEnabled method doesn't show you whether the device is supported&enabled or not. It shows whether user allowed LiveActivity.

So I solved this problem adding new method:

    func isLiveActivitySupported() -> Bool {
        var isSupported = false
        if #available(iOS 16.1, *) {
            isSupported = !ProcessInfo.processInfo.isiOSAppOnMac
        }
        return isSupported
    }

I hope this way works well.
