shell-completion: zsh: Use -S and -A with _arguments

-S makes the option parser to not try parsing arguments as options
after "--" has appeared in the command line.

-A "-*" makes the option parser to not try parsing arguments as
options after the first non-option argument. The "-*" pattern means
that if there are unrecognized parameters that look like options
(i.e. start with a dash), those should not terminate the option
parsing.
