Mark ShannonandGitHub ac7d5ba96e GH-133231: Changes to executor management to support proposed sys._jit module (GH-133287) 
* Track the current executor, not the previous one, on the thread-state. 

* Batch executors for deallocation to avoid having to constantly incref executors; this is an ad-hoc form of deferred reference counting.

 		3d4ac1a2c2 gh-123358: Use _PyStackRef in LOAD_DEREF (gh-130064) 
Concurrent accesses from multiple threads to the same `cell` object did not
scale well in the free-threaded build. Use `_PyStackRef` and optimistically
avoid locking to improve scaling.

With the locks around cell reads gone, some of the free threading tests were
prone to starvation: the readers were able to run in a tight loop and the
writer threads weren't scheduled frequently enough to make timely progress.
Adjust the tests to avoid this.

T. WoutersandGitHub de2f7da77d gh-115999: Add free-threaded specialization for FOR_ITER (#128798) 
Add free-threaded versions of existing specialization for FOR_ITER (list, tuples, fast range iterators and generators), without significantly affecting their thread-safety. (Iterating over shared lists/tuples/ranges should be fine like before. Reusing iterators between threads is not fine, like before. Sharing generators between threads is a recipe for significant crashes, like before.)
