  1. pythongh-107137: Add _PyTuple_NewNoTrack() internal C API 

    Fix a crash in PySequence_Tuple() when the tuple which is being
initialized was accessed via GC introspection, like the
gc.get_referrers() function. Now the function only tracks the tuple
by the GC once it's fully initialized.

Add _PyTuple_NewNoTrack() and _PyTuple_ResizeNoTrack() functions to
the internal C API: similar to PyTuple_New() and _PyTuple_Resize(),
but don't track the tuple by the GC.

Modify PySequence_Tuple() to use these functions.
