completion: teach archive to use __gitcomp_builtin 

Currently, _git_archive() uses a hardcoded list of options for its
completion. However, we can use __gitcomp_builtin() to get a dynamically
generated list of completions instead.

Teach _git_archive() to use __gitcomp_builtin() so that newly
implemented options in archive will be automatically completed without
any mucking around in git-completion.bash. While we're at it, teach it
to complete the missing `--worktree-attributes` option as well.

Unfortunately, since some args are passed through from cmd_archive() to
write_archive() (which calls parse_archive_args()), there's no way that a
`--git-completion-helper` arg can end up reaching parse_archive_args()
since the first call to parse_options() will end up calling exit(0). As
a result, we have to carry the options supported by write_archive() in
the hardcoded string.
