gh-126835: Move optimization of constant sequence creation from codegen to CFG (#129426) 
Codegen phase has an optimization that transforms
```
LOAD_CONST x
LOAD_CONST y
LOAD_CONXT z
BUILD_LIST/BUILD_SET (3)
```
->
```
BUILD_LIST/BUILD_SET (0)
LOAD_CONST (x, y, z)
LIST_EXTEND/SET_UPDATE 1
```
This optimization has now been moved to CFG phase to make #128802 work.

gh-129236: Use `stackpointer` in free threaded GC (#129240) 
The stack pointers in interpreter frames are nearly always valid now, so
use them when visiting each thread's frame. For now, don't collect
objects with deferred references in the rare case that we see a frame
with a NULL stack pointer.

gh-129185: Simplify PyTraceMalloc_Track() (#129256) 
Since tracemalloc uses PyMutex, it becomes safe to use TABLES_LOCK()
even after _PyTraceMalloc_Fini(): remove the "pre-check" in
PyTraceMalloc_Track() and PyTraceMalloc_Untrack().

PyTraceMalloc_Untrack() no longer needs to acquire the GIL.

_PyTraceMalloc_Fini() can be called earlier during Python
finalization.

gh-129185: Fix PyTraceMalloc_Untrack() at Python exit (#129191) 
Support calling PyTraceMalloc_Track() and PyTraceMalloc_Untrack()
during late Python finalization.

* Call _PyTraceMalloc_Fini() later in Python finalization.
* Test also PyTraceMalloc_Untrack() without the GIL
* PyTraceMalloc_Untrack() now gets the GIL.
* Test also PyTraceMalloc_Untrack() in test_tracemalloc_track_race().
