lauren 888ea60d8e [compiler][repro] Postfix operator is incorrectly compiled (#33508 )

This bug was reported via our wg and appears to only affect values
created as a ref.

Currently, postfix operators used in a callback gets compiled to:

```js
modalId.current = modalId.current + 1; // 1
const id = modalId.current; // 1
return id;
```

which is semantically incorrect. The postfix increment operator should
return the value before incrementing. In other words something like this
should have been compiled instead:

```js
const id = modalId.current; // 0
modalId.current = modalId.current + 1; // 1
return id;
```

This bug does not trigger when the incremented value is a plain
primitive, instead there is a TODO bailout.

React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.

This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
