Tim Yung f638aff434 RN: Add NativeComponentRegistry.getWithFallback_DEPRECATED
Summary:
Creates `NativeComponentRegistry.getWithFallback_DEPRECATED`. This is deprecated from inception because it exists only to support a pattern that should not be necessary.

For any given `NativeX` component, the JavaScript module that calls `NativeComponentRegistry.get('NativeX', …)` should only exist in the JavaScript bundle if the native binary actually supports that native component.

But in today's transitional state of the world, there are JavaScript modules that use `UIManager.getViewManagerConfig('NativeX')` as a means of feature detection.

The purpose of `NativeComponentRegistry.getWithFallback_DEPRECATED` is to bridge this transitional gap. Component should migrate toward initializing the `NativeComponentRegistry` with a runtime configuration provider that enumerates all supported native components. If the native component is not supported, it should return null.

Tim Yung 6a547c6c57 RN: Create NativeComponentRegistry
Summary:
Creates `NativeComponentRegistry` which makes native component initialization more declarative and configurable through an optionally configurable provider.

The next diff converts `ScrollView` to use this new abstraction as a demonstration. The plan would be to use this to replace all current manual call sites of `registerGeneratedViewConfig`, and then the ones generated via the Babel plugin.

Migrating to this will not change any production behavior, but it will enable verification of `ViewConfig` in development.
