Fix onLayout prop for TextInput on Android

Summary:
When the `autogrow` prop was removed from `TextInput` on Android, the `_onLayout` helper method was removed. This helper method implemented the hook required to make `autogrow` work, then dispatched the `onLayout` event to the handler in `this.props`. This change points passes the `onLayout` handler from `this.props` directly to the inner component.
