Summary: Android API 15 still have 1.5~2.0% distribution (refer: [Dashboard - Android Developer](https://developer.android.com/ndk/guides/standalone_toolchain.html#creating_the_toolchain)). React Native is a good tec but many companies cannot endure loose their consumer. [Choreographer](https://developer.android.com/reference/android/view/Choreographer.html) triggered UI operation is the only reason that React Native Android sdk use minSdkVersion 16, so we can use a backward solution **only in API 15**: [Handler](https://developer.android.com/reference/android/os/Handler.html). In this PR, the biggest change is : - Make core operation of ReactChoreographer to an interface: ReactUIDriver; - Impl ReactUIDriver by Handler => UIDriverHandlerImpl, refactor ReactChoreographer to UIDriverChoreographerImpl; - Let UIDriverFactory to choose which one impl would be in use. (Only use handler in api 15).
