Jorge Cabiedes Acosta 663ddab596 [compiler] Prevent overriding a derivationEntry on effect mutation and instead update typeOfValue and fix infinite loops

Summary:
With this we are now comparing a snapshot of the derivationCache with the new changes every time we are done recording the derivations happening in the HIR.

We have to do this after recording everything since we still do some mutations on the cache when recording mutations.



Test Plan:
Test the following in playground:
```
// @validateNoDerivedComputationsInEffects_exp

function Component({ value }) {
  const [checked, setChecked] = useState('');

  useEffect(() => {
    setChecked(value === '' ? [] : value.split(','));
  }, [value]);

  return (
    <div>{checked}</div>
  )
}
```

This no longer causes an infinite loop.

Added a test case in the next PR in the stack

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
