Summary:
In React Native there are three types of "Native" components.
```
createReactClass with NativeMethodsMixin
```
```
class MyComponent extends ReactNative.NativeComponent
```
```
requireNativeComponent('RCTView')
```
The implementation for how to handle all three of these exists in the React Native Renderer. Refs attached to components created via these methods provide a set of functions such as
```
.measure
.measureInWindow
.measureLayout
.setNativeProps
```
These methods have been used for our core components in the repo to provide a consistent API. Many of the APIs in React Native require a `reactTag` to a host component. This is acquired by calling `findNodeHandle` with any component. `findNodeHandle` works with the first two approaches.
For a lot of our new Fabric APIs, we will require passing a ref to a HostComponent directly instead of relying on `findNodeHandle` to tunnel through the component tree as that behavior isn't safe with React concurrent mode.
The goal of this change is to enable us to differentiate between components created with `requireNativeComponent` and the other types. This will be needed to be able to safely type the new APIs.
For existing components that should support being a host component but need to use some JS behavior in a wrapper, they should use `forwardRef`. The majority of React Native's core components were migrated to use `forwardRef` last year. Components that can't use forwardRef will need to have a method like `getNativeRef()` to get access to the underlying host component ref.
Note, we will need follow up changes as well as changes to the React Renderer in the React repo to fully utilize this new type.

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary: Apparently different apps have different implementations of view managers that support different props. This is a problem that we will need to address. Unfortunately, this means we can't have a static config defined in JS. We will need to find another approach to this problem.

Summary: Moving this config to native for android so we skip the native lookup for the config.
