RN: Remove Native Prop Validation

Summary:
As we migrate over to static typing solutions for props, we cannot rely on always having `propTypes` available at runtime.

This gets us started on that journey by removing the native prop validation that happens when we require native components.

 /**
- * Used to create React components that directly wrap native component
- * implementations.  Config information is extracted from data exported from the
- * UIManager module.  You should also wrap the native component in a
- * hand-written component with full propTypes definitions and other
- * documentation - pass the hand-written component in as `componentInterface` to
- * verify all the native props are documented via `propTypes`.
+ * Creates values that can be used like React components which represent native
+ * view managers. You should create JavaScript modules that wrap these values so
+ * that the results are memoized. Example:
  *
- * If some native props shouldn't be exposed in the wrapper interface, you can
- * pass null for `componentInterface` and call `verifyPropTypes` directly
- * with `nativePropsToIgnore`;
+ *   const View = requireNativeComponent('RCTView');
  *
- * Common types are lined up with the appropriate prop differs with
- * `TypeToDifferMap`.  Non-scalar types not in the map default to `deepDiffer`.
