Move TupledFunctions to standard directory

For discussion:

• Do we really need it? How useful they are in practice.

  For example, stdlib only defines such methods up to arity 5

• What about other operations? Such as, curried and uncurried?

• Rename TupledFunction to FunctionTupling?

[nicolasstucki]

TupledFuntions are there to support generic function application of any arity. I guess we could be added later to the language when someone finds the need for this feature.

[nicolasstucki]

The name was chosen to be aligned with FuntionN.tupled.

[nicolasstucki]

I believe we can encode curry and uncurry using TupledFunction and *:.

I created #10411 to discuss this further
