xkbcommon
tools: add zsh completions
N.B. To try it out place the completion script called "_xkbcli" somewhere in your $fpath.
Please check that the meson bits are reasonable.
I like to provide completions for the layouts/models/options, etc. but not sure there's a good way without parsing xkbcli output with yq or something. I don't particularly mind doing that, but obviously its better if we don't depend on an external tool.
Do you think it would be possible to give xkbcli a more shell-parse friendly output?
The options RMLVO completer isn't working perfectly, as the group names don't always match the options prefixes:
$ XKB_DEFAULT_OPTIONS=<TAB>
altwin -- Alt and Win behavior
caps -- Caps Lock behavior
compat -- Compatibility options

ctrl -- Ctrl position
currencysign -- Currency signs

$ XKB_DEFAULT_OPTIONS=compat:<TAB> # these aren't real options since they don't actually being with "compat:"
alupckeys -- Apple Aluminium emulates Pause, PrtSc, Scroll Lock

I'll think of a better way to present these completions.
