Anton Chesnokov 22a20e1f2f [compiler] Fix setState-in-effect for React.useEffect namespace calls (#35377) (#35419)
## Summary
Fix react-hooks/set-state-in-effect false negatives when Hooks are
called via a namespace import (e.g. `import * as React from 'react'` and
`React.useEffect(...))`. The validation now checks the MethodCall
property (the actual hook function) instead of the receiver object.

Issue: Bug: #35377

## How did you test this change?
Added a regression fixture;
Ran tests and verified it reports `EffectSetState` and matches the
expected output.

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
