Convert error and immutable to builtin functions

I'm trying to understand why error
and immutable
and are keywords. It's quite easy to convert them to builtins, and there are a few reasons to do so:
- Those two and
import
are the only keywords which behave like functions. - Casting to other types utilises builtin functions, not keywords.
error
isn't a keyword in golang.error
is a method name in some popular libraries (e.g.: by resty, logrus), and since tengo doesn't allow using keywords as selectors #301, it makes using them difficult.
The only downside I see is a negligible performance hit, since those function calls are made in a run time.
