Remove the builtin empty tuple value (not type). (#2850)

Browse Source 
We do use the empty tuple type for function returns, so I don't want to get rid of it, but the value is unused. With this change, builtins are all types. Long-term the empty tuple value should have a representation similar to structs; just a tuple value that's empty, not a built-in.
