Joseph SavonaandGitHub 7899729130 [compiler] Option to treat "set-" prefixed callees as setState functions (#34505 )

Calling setState functions during render can lead to extraneous renders
or even infinite loops. We also have runtime detection for loops, but
static detection is obviously even better.

This PR adds an option to infer identifers as setState functions if both
the following conditions are met:
- The identifier is named starting with "set"
- The identifier is used as the callee of a call expression

By inferring values as SetState type, this allows our existing
ValidateNoSetStateInRender rule to flag calls during render, disallowing
examples like the following:

```js
function Component({setParentState}) {
  setParentState(...);
  ^^^^^^^^^^^^^^ Error: Cannot call setState in render
}
```

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
