Summary:
Adding runtime type information adds greatly to the binary size, so react-native-windows builds without it. But some parts of the fabric code currently uses dynamic_cast, which means to use fabric we have to build with RTTI turned on. This PR removes the usages of dynamic_cast that are hit in release builds, which should allow react-native-windows to turn off RTTI in release builds.
Required for: https://github.com/microsoft/react-native-windows/issues/7981
One thing to note, the comment in ShadowNodeTraits indicates that core was reserving the first 16 bits. I'm adding two more. Is that ok? Should core be reserving more for future use?
