Subject: distutils*.bbclass: move from oe-core

distutils has been deprecated in Python 3.10 and will be removed in
Python 3.12 (predicted release date October 2023). For now, move these
classes from oe-core to allow users to migrate.

A deprecation warning has been added to each class.

Documentation is also being dropped in oe-core, but users can refer to
3.4 documentation for the legacy variables and classes.

[YOCTO #14610]
