gh-111178: Fix function signatures in longobject.c (#124895) 
* Add _PyLong_CAST() macro.
* Move forward declarations to the top of longobject.c.
* Change long_add(), long_sub(), long_mul(), long_neg(),
  long_lshift(), long_abs() to take PyLongObject* and return
  PyLongObject*. Avoid CHECK_BINOP() test.
* Add long_add_method(), long_sub_method(), long_mul_method(),
  long_neg_method(), long_lshift_method(), and long_abs_method()
  which take PyObject* and return PyObject*. Implement CHECK_BINOP()
  test.
* Add long_lshift_int64() function.
* _PyLong_DivmodNear() calls long_lshift_int64(obj, 1) instead of
  long_lshift_obj(obj, one).

gh-123497: New limit for Python integers on 64-bit platforms (GH-123724) 
Instead of be limited just by the size of addressable memory (2**63
bytes), Python integers are now also limited by the number of bits, so
the number of bit now always fit in a 64-bit integer.

Both limits are much larger than what might be available in practice,
so it doesn't affect users.

_PyLong_NumBits() and _PyLong_Frexp() are now always successful.

gh-121485: Always use 64-bit integers for integers bits count (GH-121486) 
Use 64-bit integers instead of platform specific size_t or Py_ssize_t
to represent the number of bits in Python integer.

gh-106320: Re-add some PyLong/PyDict C-API functions (GH-#111162) 
* gh-106320: Re-add _PyLong_FromByteArray(), _PyLong_AsByteArray() and _PyLong_GCD() to the public header files since they are used by third-party packages and there is no efficient replacement.

See https://github.com/python/cpython/issues/111140
See https://github.com/python/cpython/issues/111139

* gh-111262: Re-add _PyDict_Pop() to have a C-API until a new public one is designed.

gh-106320: Remove private _PyLong_FileDescriptor_Converter() (#108503) 
Move the private _PyLong converter functions to the internal C API

* _PyLong_FileDescriptor_Converter(): moved to pycore_fileutils.h
* _PyLong_Size_t_Converter(): moved to pycore_long.h

Argument Clinic now emits includes for pycore_fileutils.h and
pycore_long.h when these functions are used.
