Carwyn Nelson a2591bc5fa LibCore: Make ArgParser::Arg::accept_value return ErrorOr<bool> ...

Much like the previous commit, this commit makes the
ArgParser::Arg::accept_value callback return an ErrorOr<bool> instead of
just a bool.

The aim of this is to make argument parsing more robust, especially
with the newer String api that returns an ErrorOr for many functions.
