The current internal isError function checked the toString value
instead of using the more precise util.types.isNativeError() check.
The instanceof check is not removed due to possible errors that
are not native but still an instance of Error.

The internal isError function is only used in util.inspect() and the repl.

Checklist

I think this should have some unit tests, specifically, some that failed before the change and succeed afterwards. My js isn't good enough, I don't understand the subtleties of how it is becoming more precise, and was hoping to learn what corner cases are better covered from the tests.
