Joe Savona 9db3f8b484 Update on "[compiler] Null out source locations where not explicitly preserved"

Inspired by #32950. Specifically from https://github.com/facebook/react/issues/32950#issuecomment-2837887871, it sounds like Babel by default emits source map information for all nodes, even when they don't have a `loc` property set. Code coverage tools then pick up the synthesized source location information for this, leading to the issue described.

A few google searches didn't turn up any documented way to opt-out of generating source span information, but AI tools answer that explicitly setting `node.loc = null` omits the node from source maps. This PR is a quick hack to confirm that.

babel-plugin-react-compiler

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
