refactor: remove TupleLike

* Directly transform VIATRA tuples into Refinery tuples, since creating
  the additional wrapper object doesn't save any memory.
* Adds static arity Tuple3 and Tuple4 implementations to be more
  aligned with VIATRA internals and save memory for queries with up to
  4 parameters.
* Makes sure no new objects are allocated (for varargs handling) when a
  static arity tuple is hashed.
