The completion for 'git stash' has not changed in a major way since it
was converted from shell script to builtin. Now that it's a builtin, we
can take advantage of the groundwork laid out by parse-options and use
the generated options.

Rewrite _git_stash() to take use __gitcomp_builtin() to generate
completions for subcommands.

The main `git stash` command does not take any arguments directly. If no
subcommand is given, it automatically defaults to `git stash push`. This
means that we can simplify the logic for when no subcommands have been
given yet. We only have to offer subcommand completions when we're
completing the word after "stash". Unfortunately, this does not work
100% correctly. For example, in the case of something like `git -C stash
stash<TAB>`, this will incorrectly identify the first "stash" as the
command. This seems to be an edge-case that we can ignore, though, as
other functions, such as _git_worktree(), suffer from the same problem.

One area that this patch could improve upon is that the `git stash list`
command accepts log-options. It would be nice if the completion for this
were unified with that of _git_log() and _git_show() which would allow
completions to be provided for options such as `--pretty` but that is
outside the scope of this patch.
