Janic Duplessis ae756647c9 Fix babel-plugin-codegen crash when export init is null (#33387) ...

Summary:
It is possible that `init` is null when using the following code.

```js
export var a;
```

The typescript compiler actually generates something like this for enums so a lot of third party libraries triggered this issue.

For example in expo-apple-authentication/build/AppleAuthentication.types.js

```js
export var AppleAuthenticationScope;
(function (AppleAuthenticationScope) {
    AppleAuthenticationScope[AppleAuthenticationScope["FULL_NAME"] = 0] = "FULL_NAME";
    AppleAuthenticationScope[AppleAuthenticationScope["EMAIL"] = 1] = "EMAIL";
})(AppleAuthenticationScope || (AppleAuthenticationScope = {}));
```

This simply adds a null check.
