gh-128130: Fix unhandled keyboard interrupt data race (gh-129975) 
Use an atomic operation when setting
`_PyRuntime.signals.unhandled_keyboard_interrupt`. We now only clear the
variable at the start of `_PyRun_Main`, which is the same function where
we check it.

This avoids race conditions where previously another thread might call
`run_eval_code_obj()` and erroneously clear the unhandled keyboard
interrupt.

gh-129668: Fix thread-safety of MemoryError freelist in free threaded build (gh-129704) 
The MemoryError freelist was not thread-safe in the free threaded build.
Use a mutex to protect accesses to the freelist. Unlike other freelists,
the MemoryError freelist is not performance sensitive.

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-128954: Reorder _PyInterpreterFrame fields for reduced memory usage (#128958) 
This reduces the size of _PyInterpreterFrame by 8 bytes on 64-bit
platforms using the free threading build due to alignment requirements.

This allows for slightly more recursive calls into the interpreter (from
C), but `test_call.test_super_deep` still crashes.

gh-128923: Use zero to indicate unassigned unique id (#128925) 
In the free threading build, the per thread reference counting uses a
unique id for some objects to index into the local reference count
table. Use 0 instead of -1 to indicate that the id is not assigned. This
avoids bugs where zero-initialized heap type objects look like they have
a unique id assigned.
