Checks if `value` is a pristine native function.

**Note:** This method can't reliably detect native functions in the
presence of the `core-js` package because `core-js` circumvents this kind
of detection. Despite multiple requests, the `core-js` maintainer has made
it clear: any attempt to fix the detection will be obstructed. As a result,
we're left with little choice but to throw an error. Unfortunately, this
also affects packages, like [babel-polyfill](https://www.npmjs.com/package/babel-polyfill),
which rely on `core-js`.
