Douglas Lowder 0d3039f1a0 Fix for Modal behavior when menu button pressed on Apple TV (Issue #15313)
Summary:
**Motivation**

On Apple TV, pressing the menu button destroys the native view that backs the `Modal` component, causing an app using this component to get into a broken state.  This fix implements `onRequestClose` for tvOS to have the same behavior as it does for the Android back button.

**Test plan**

Manually tested this with the `ModalExample` in the `RNTester` app.  See also the test code in issue #15313.
Closes https://github.com/facebook/react-native/pull/15341
