[compiler][rfc] Enable hook guards in dev mode by default

This validation ensures that React compiler-enabled apps remain correct. That is, code that errors with this validation is most likely ***invalid*** with React compiler is enabled (specifically, hook calls will be compiled to if-else memo blocks).

Hook guards are used extensively for Meta's react compiler rollouts. There, they're enabled for developers (for dev builds) and on e2e test runs. Let's enable by default for oss as well

### Examples of inputs this rule throws on

* Components should not be invoked directly as React Compiler could memoize the call to AnotherComponent, which introduces conditional hook calls in its compiled output.
  ```js
  function Invalid1(props) {
   const myJsx = AnotherComponent(props);
   return <div> { myJsx } </div>;
  }
  ```
* Hooks must be named as hooks. Similarly, hook calls may not appear in functions that are not components or hooks.
  ```js
  const renamedHook = useState;
  function Invalid2() {
    const [state, setState] = renamedHook(0);
  }

  function Invalid3() {
    const myFunc = () => useContext(...);
    myFunc();
  }
  ```

* Hooks must be directly called (from the body of a component or hook)
  ```
  function call(fn) {
    return fn();
  }

  function Invalid4() {
    const result = call(useMyHook);
  }
  ```

- * MixedReadOnly =

- *   | Array<MixedReadOnly>
- *
- * APIs such as Relay — but also Flux and other data stores — often return a
- * union of types with some interesting properties in terms of analysis.
- *
- * Given this constraint, if data came from Relay, then we should be able to
- * infer things like `data.items.map(): Array`. That may seem like a leap at
- * first but remember, we assume you're not patching builtins. Thus the only way
- * data.items.map can exist and be a function, given the above set of data types
- * and builtin JS methods, is if `data.items` was an Array, and `data.items.map`
- * is therefore calling Array.prototype.map. Then we know that function returns
- * an Array as well. This relies on the fact that map() is being called, so if
- * data.items was some other type it would error at runtime - so it's sound.
- *
- * Note that this shape is currently only used for hook return values, which
- * means that it's safe to type aliasing method-call return kinds as `Frozen`.
- *
- * Also note that all newly created arrays from method-calls (e.g. `.map`)
- * have the appropriate mutable `BuiltInArray` shape
