Joseph Savona 724b324b96 [compiler] Add hint to name variables with "Ref" suffix (#34125 )

If you have a ref that the compiler doesn't know is a ref (say, a value
returned from a custom hook) and try to assign its `.current = ...`, we
currently fail with a generic error that hook return values are not
mutable. However, an assignment to `.current` specifically is a very
strong hint that the value is likely to be a ref. So in this PR, we
track the reason for the mutation and if it ends up being an error, we
use it to show an additional hint to the user. See the fixture for an
example of the message.

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
