Add support for browserslist and legacyBrowsers experimental option (#36584)
Implements the first part of #33227

- Applies browserslist to JS transforms when `experimental.browsersListForSwc` is enabled. 
- You don't have to use browserslist, there's also `legacyBrowsers: false` which will be the new default in Next.js 13. See #33227 for which browsers and why. `legacyBrowsers` requires `browsersListForSwc: true` to function until it is the default. 

```js
module.exports = {
  experimental: {
    legacyBrowsers: false,
    browsersListForSwc: true,
  }
}
```

I only implemented the JS part of the RFC, the CSS part should be handled in a follow-up PR.
