completion: make bash completion work in zsh

Browse Source 
`compgen -W` does not behave the same way in zsh as it does in bash; it seems not to
actually generate the completions we want.

- [x] add a zsh equivalent and `_compgen_w` to abstract it away
- [x] use `_compgen_w` instead of `compgen -W`
