Support enums within tables

This may have to be a follow-up of https://github.com/sumneko/lua-language-server/issues/1411 but I have created this as a separate issue for separate feedback & tracking purposes

It would be nice if we could have enum function argument suggestions based on where the enumerator is defined. Currently, if you have an enum nested within some tables, it will only suggest the enum values as such:

This is fine if using the values defined directly is not an issue. However, if the enum values are runtime values (as mentioned in issue https://github.com/sumneko/lua-language-server/issues/1411) then we'd like to have some sort of initial auto-complete as such:

I am not sure how expensive computationally it may be to do this, if that is an issue then perhaps there exists a cheap workaround that could be used for documenting purposes.

Lisez l’issue #1411 avec cette issue pour comprendre la limitation liée à runtime-value et le contexte de suivi demandé. Utilisez les exemples et les captures d’écran de nested-table enums comme référence du comportement. Le travail est terminé lorsque la complétion des arguments de fonction peut suggérer des valeurs d’enum en fonction de l’endroit où l’énumérateur est défini, y compris les enums imbriqués dans des tables.
