[OE-core][PATCH 5/6 v3] python3: add _py_warnings, annotationlib to core

[Trevor Gamblin <tgamblin@baylibre.com>]

Without adding these, there will be numerous packages that will have to
add python3-misc to their RDEPENDS just to dispel some warnings, like:

|root@qemux86-64:~# python3
|Python 3.14.2 (main, Dec  5 2025, 16:49:16) [GCC 15.2.0] on linux
|Type "help", "copyright", "credits" or "license" for more information.
|warning: can't use pyrepl: No module named 'annotationlib'

and errors like:

|>>> import logging
|Traceback (most recent call last):
|  File "<stdin-1>", line 1, in <module>
|  File "/usr/lib/python3.14/logging/__init__.py", line 26, in <module>
|    import sys, os, time, io, re, traceback, warnings, weakref, collections.abc
|  File "/usr/lib/python3.14/traceback.py", line 8, in <module>
|    import warnings
|  File "/usr/lib/python3.14/warnings.py", line 15, in <module>
|    from _py_warnings import (
|ModuleNotFoundError: No module named '_py_warnings'

Add them to python3-core rather than requiring another split.
