FeatureReq: Additional IntelliSense Help for Functions w/RETURNs

[DyoungMCWI]

Describe the solution you'd like
FUNCTION definitions can include a RETURN value. When typing the function name, it would ne nice if IntelliSense would provide additional context to suggest that a function has a return value.

Describe possible alternatives you've considered
N/A

Additional context
Particularly helpful for externally defined functions where the function definition isn't readily available.

My long term goal for user defined functions is probably more aligned with incorporating some form of JSDOC like you have been doing in the FabricationDefinitions.ts file. I see your point and agree, but I think making educated guesses about the intended data types could easily backfire. Probably more so should we next try to deploy that same kind of logic on argument data types. IE, they could technically mutate throughout a script.
Keep this here as a reminder, but its probably coming in a different form.
