crypto: extract throwInvalidArgType function

This commit extracts the throwing of ERR_INVALID_ARG_TYPE which is done
in identical ways in a few places in cipher.js.

The motivation for this is that I think it improves readability enough to
warrant a commit even though I'm aware that we should avoid commits with
only these sort of refactoring.
