Add command line completion in zsh for the "code" command

[Mellbourn]

Feature request:

I think it would be nice if vscode included zsh command line completions for the code command. So I've implemented that in this script https://github.com/Mellbourn/dotfiles/blob/master/.zsh-personal-completions/_code.
This implementation gives completion for all documented parameters and has specialized completion for parameters that don't take filenames as parameters, for example --add only take directories as arguments.
I have tested that it works well on macOS and Windows Subsystem for Linux (Ubuntu).

I will gladly submit this file as part of a pull request.

However, this file needs to be in the PATH or fpath environment variable if it is to take effect in zsh. Unfortunately I have no good idea how to implement the deploy mechanism to achieve that.

I am very open to suggestions on how to proceed.

@Mellbourn We suggest to provide this as an external tool. Pretty cool stuff!

@joaomoreno Makes sense. I think I'll submit it to https://github.com/zsh-users/zsh-completions (a large library of completions for zsh).

That'd be awesome!

FYI: This script has now been added to the official zsh distribution. zsh-users/zsh@5e10acc

Feel free to ping me if the command line interface changes, and I'll update the completion script.
