Adam Comella 4d2c72b977 NavigatorIOS: Expose interactivePopGestureEnabled property
Summary:
Previously, the back swipe navigation gesture would be enabled when the navigation bar is shown and disabled when the navigation bar is hidden.

This change enables developers to control the back swipe gesture independently of the visibility of the navigation bar. An example use case would be that an app wants to render a custom navigation bar so it sets `navigationBarHidden` to true and it wants to enable the back swipe gesture so it sets `interactivePopGestureEnabled` to true.

**Test plan (required)**

- Created a test app to verify setting `interactivePopGestureEnabled` to `true` and `false` with the navigation bar both hidden and shown.
- Verified prop works in a larger app.
