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.

Lee el issue #1411 junto con este issue para entender la limitación de runtime-value y el contexto de seguimiento solicitado. Usa los ejemplos y las capturas de pantalla de nested-table enums como referencia del comportamiento. Se considera terminado cuando la finalización de argumentos de función puede sugerir valores de enum según dónde esté definido el enumerador, incluidos los enums anidados dentro de tablas.
