Summary:
Fabric core uses a lot of traits - I am reserving a few more for core usage, and also exposing a few "unreserved" traits.
It is recommended that all custom components that do use traits rely on these constants instead of hard-coding any trait values. That way, in the unlikely event that these values change in the future, it will not break components.

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?

[Internal] [Fixed] - Remove uses of dynamic_cast in release builds
Pull Request resolved: https://github.com/facebook/react-native/pull/31694
Test Plan:
Verified that I can build react-native-windows with Fabric in release, without RTTI.

Summary:
This implements the `MeasurableYogaNode` trait in `YogaLayoutableShadowNode`. We had this trait from the very beginning but never used it. Now, if the trait is specified, `YogaLayoutableShadowNode` will set the measure function for the node and dirty it during cloning.
Previously, we used (and still use) a dedicated method for setting up the measure function - `YogaLayoutableShadowNode::enableMeasurement()`. The problem with it is that to make it work we have to dirty the Yoga node every time we clone it. And the only proper way to do this in the `YogaLayoutableShadowNode` constructor because if we do it later ancestor nodes could not observe this and react to this. Therefore we have to have a trait for it.
The plan is to use it for TextInput first to fix a crash (see the next diff). After we confirm it works fine, we will replace all the usages of `enableMeasurement` with the new trait.
This diff also renames the other two yoga-related traits (to make them less verbose and look unified), adds more comments, and asserts.

Summary:
This implements a new ShadowNode trait that helps to propagate Yoga node `isDirty` flag down the root of the tree and clone siblings appropriately.
Several Fabric components mutate its Yoga styles after the node was cloned. In such cases, we need to mark the node as dirty after doing so. The problem with this is that the parent node and its siblings were already updated (cloned or not) based on the previous value of the `isDirty` flag. This happens because this logic is implemented in YogaLayoutableShadowNode which is a base constructor that must be called before any other logic from a subclass can run.
For now, this change enables that for SafeAreaView only (which seems to help with some junkiness issues), later we can extend the usage of this for other components if needed.

Summary:
This diff removes the inner folder of react/renderer/core, moving all its files into react/renderer/core
This is necessary to simplify the compilation of Fabric in OSS
