box/lua: allow to set error cause via `prev` argument

Currently, it's only possible to set an error cause with the set_prev
method. This isn't very convenient, because one has to construct a new
error without raising it, then set its cause, and only then raise it.
To simplify this, a new argument `prev` is added to the error constructor.

Closes #9103
