[NUI] Support LottieAnimationView file load asynchronously

Current LottieAnimationView implement their own ViewCreation logic.

For example, ImageView.ResourceUrl = ~~ didn't change synchronously option.
But LottieAnimationView.ResourceUrl = ~~~ make synchronously option as true hardly.

So, there is no way to make asynchronously load lottie file.

To support it, let we cherry-pick new option of SynchronousLoading.
