gh-108867: Add PyThreadState_GetUnchecked() function (#108870)

Browse source 
Add PyThreadState_GetUnchecked() function: similar to
PyThreadState_Get(), but don't issue a fatal error if it is NULL. The
caller is responsible to check if the result is NULL. Previously,
this function was private and known as _PyThreadState_UncheckedGet().

When the current thread state is ``NULL``, this issues a fatal error (so that
the caller needn't check for ``NULL``).
See also :c:func:`PyThreadState_GetUnchecked`.
.. c:function:: PyThreadState* PyThreadState_GetUnchecked()
Similar to :c:func:`PyThreadState_Get`, but don't kill the process with a
fatal error if it is NULL. The caller is responsible to check if the result
is NULL.

In Python 3.5 to 3.12, the function was private and known as
``_PyThreadState_UncheckedGet()``.
