zsh_completion: update all options

It's just too hard to further split this patch. What it does:

- adds missing flags
- removes flags that are no longer there
- updates flag descriptions and argument names
- adds * where using the same option many times is okay
- groups with () mutually exclusive flags that can't be used together
- adds + and = to options that need arguments
- removes + and = from options that don't take any arguments
- fixes minor issues and a typo
