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.

gh-120321: Make gi_frame_state transitions atomic in FT build (gh-142599)
...
This makes generator frame state transitions atomic in the free
threading build, which avoids segfaults when trying to execute
a generator from multiple threads concurrently.
There are still a few operations that aren't thread-safe and may crash
if performed concurrently on the same generator/coroutine:
* Accessing gi_yieldfrom/cr_await/ag_await
* Accessing gi_frame/cr_frame/ag_frame
* Async generator operations
