Two related changes:
* ValidateNoRefAccessInRender now allows the mergeRefs pattern, ie a
function that aggregates multiple refs into a new ref. This is the main
case where we have seen false positive no-ref-in-render errors.
* Behind `@enableTreatRefLikeIdentifiersAsRefs`, we infer values passed
as the `ref` prop to some JSX as refs.
The second change is potentially helpful for situations such as
```js
function Component({ref: parentRef}) {
const childRef = useRef(null);
const mergedRef = mergeRefs(parentRef, childRef);
useEffect(() => {
// generally accesses childRef, not mergedRef
}, []);
return <Foo ref={mergedRef} />;
}
```
Ie where you create a merged ref but don't access its `.current`
property. Without inferring `ref` props as refs, we'd fail to allow this
merge refs case.

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
