parse-options: support --git-completion-helper

This option is designed to be used by git-completion.bash. For many
simple cases, what we do in there is usually

__gitcomp "lots of completion options"

which has to be manually updated when a new user-visible option is
added. With support from parse-options, we can write

__gitcomp "$(git command --git-completion-helper)"

and get that list directly from the parser for free. Dangerous/Unpopular
options could be hidden with the new "NOCOMPLETE" flag.
