gh-105858: Improve AST node constructors (#105880) 
Demonstration:

>>> ast.FunctionDef.__annotations__
{'name': <class 'str'>, 'args': <class 'ast.arguments'>, 'body': list[ast.stmt], 'decorator_list': list[ast.expr], 'returns': ast.expr | None, 'type_comment': str | None, 'type_params': list[ast.type_param]}
>>> ast.FunctionDef()
<stdin>:1: DeprecationWarning: FunctionDef.__init__ missing 1 required positional argument: 'name'. This will become an error in Python 3.15.
<stdin>:1: DeprecationWarning: FunctionDef.__init__ missing 1 required positional argument: 'args'. This will become an error in Python 3.15.
<ast.FunctionDef object at 0x101959460>
>>> node = ast.FunctionDef(name="foo", args=ast.arguments())
>>> node.decorator_list
[]
>>> ast.FunctionDef(whatever="you want", name="x", args=ast.arguments())
<stdin>:1: DeprecationWarning: FunctionDef.__init__ got an unexpected keyword argument 'whatever'. Support for arbitrary keyword arguments is deprecated and will be removed in Python 3.15.

  readline), go into the `tokenizer` directory and include logic for
  creating a lexer instance and managing the buffer for different modes.

  are already defined, like the __NEED_pthread_t macro.

GH-91079: Rename C_RECURSION_LIMIT to Py_C_RECURSION_LIMIT (#108507) 
Symbols of the C API should be prefixed by "Py_" to avoid conflict
with existing names in 3rd party C extensions on "#include <Python.h>".

test.pythoninfo now logs Py_C_RECURSION_LIMIT constant and other
_testcapi and _testinternalcapi constants.

gh-108767: Replace ctype.h functions with pyctype.h functions (#108772) 
Replace <ctype.h> locale dependent functions with Python "pyctype.h"
locale independent functions:

* Replace isalpha() with Py_ISALPHA().
* Replace isdigit() with Py_ISDIGIT().
* Replace isxdigit() with Py_ISXDIGIT().
* Replace tolower() with Py_TOLOWER().

Leave Modules/_sre/sre.c unchanged, it uses locale dependent
functions on purpose.

Include explicitly <ctype.h> in _decimal.c to get isascii().
