Remove the PyUnicode_InternImmortal() function and the
SSTATE_INTERNED_IMMORTAL macro.

The PyUnicode_InternImmortal() function is still exported in the
stable ABI. The function is removed from the API.

PyASCIIObject.state.interned size is now a single bit, rather than 2
bits.

Keep SSTATE_NOT_INTERNED and SSTATE_INTERNED_MORTAL macros for
backward compatibility, but no longer use them internally since the
interned member is now a single bit and so can only have two values
(interned or not interned).

Update stats of _PyUnicode_ClearInterned().

Use the same type that PyUnicode_FromKindAndData() kind parameter
type (public C API): int.

…erator. (GH-92722)

In the limited C API version 3.12, PyUnicode_KIND() is now
implemented as a static inline function. Keep the macro for the
regular C API and for the limited C API version 3.11 and older to
prevent introducing new compiler warnings.

Update _decimal.c and stringlib/eq.h for PyUnicode_KIND().

Rewrite test_cppext to run in a virtual environment and to build the
C++ extension with setuptools rather than distutils.

The `utc_to_seconds` call can fail, here's a minimal reproducer on
Linux:

TZ=UTC python -c "from datetime import *; datetime.fromtimestamp(253402300799 + 1)"

The old behavior still raised an error in a similar way, but only
because subsequent calculations happened to fail as well. Better to fail
fast.

This also refactors the tests to split out the `fromtimestamp` and
`utcfromtimestamp` tests, and to get us closer to the actual desired
limits of the functions. As part of this, we also changed the way we
detect platforms where the same limits don't necessarily apply (e.g.
Windows).

As part of refactoring the tests to hit this condition explicitly (even
though the user-facing behvior doesn't change in any way we plan to
guarantee), I noticed that there was a difference in the places that
`datetime.utcfromtimestamp` fails in the C and pure Python versions, which
was fixed by skipping the "probe for fold" logic for UTC specifically —
since UTC doesn't have any folds or gaps, we were never going to find a
fold value anyway. This should prevent some failures in the pure python
`utcfromtimestamp` method on timestamps close to 0001-01-01.

There are two separate news entries for this because one is a
potentially user-facing change, the other is an internal code
correctness change that, if anything, changes some error messages. The
two happen to be coupled because of the test refactoring, but they are
probably best thought of as independent changes.

# Fix typo in argparse docs.

Mixture between plural and singular forms is incorrect. Use singular consistently since typically only a single argument list is employed. Change to:

> Sometimes, when dealing with a particularly long argument list, [...]

No issue was opened, since this is a trivial change.

Use _Py_CAST() and _Py_STATIC_CAST() in macros wrapping static inline
functions of unicodeobject.h.

Change also the kind type from unsigned int to int: same parameter
type than PyUnicode_FromKindAndData().

The limited API version 3.11 no longer casts arguments to expected
types.

The limited C API version 3.12 no longer casts the argument.
