GH-143493: Conform to spec for generator expressions while supporting virtual iterators (GH-143569) 
* Moves the `GET_ITER` instruction into the generator function preamble.
  This means the the iterable is converted into an iterator during generator
  creation, as documented, but keeps it in the same code object allowing
  optimization.
