Assuming that your shell is bash, it comes from the bash tab
completion function, which has an optional package:

bash-completion/stable,now 1:2.11-6 all 
  programmable completion for the bash shell

and many packages add such completions to that, if available.


Read up on how it works in `man bash` under the title
Programmable Completion.
