Add flip operator refactoring

✅ Viability Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, new syntax sugar for JS, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

⭐ Suggestion

Implement flip operator refactoring for swapping left and right operands and update operator if needed.

This small feature would make some refactorings, that require copy-pasting operands and operators much easier.

📃 Motivating Example

Before:

// harder to understand
if (5 < position) {
    // ...
}

After:

// much easier
if (position > 5) {
    // ...
}
