lang/python311: Update to 3.11.3

lang/python311: add LibreSSL support

LibreSSL 3.6 and later are fully compatible with PEP-644 for the
ssl and hmac modules, but not hashlib due to missing SHA-3/SHAKE,
BLAKE2 and scrypt. Partially reverts
https://github.com/python/cpython/commit/39258d3595300bc7b952854c915f63ae2d4b9c3e
for _hashopenssl.c only and void the configure check so that hashlib
builds on LibreSSL.

lang/python: restore USES=python variables and SUB_LIST (no-op)

Has been a to do item for time. These are independent from but used
by the bytecode trigger.

lang/python: Revert "add bytecode trigger"

This reverts commit c17ddfbf66e2801ec620d49979aca3d7077d7002.

This causes breakage on several ports, and the next iteration
requires a full exp-run. See:

lang/python3: allow using LTO on powerpc64

It was recently fixed and will be available in 13.2-RELEASE.
Since LTO is not enabled by default, it's ok to make it available.

lang/python: add bytecode trigger

Facilitates compiling, writing and removing bytecode files (.pyc)
in site-packages after all pkg transactions have been completed.

Technical details: https://wiki.freebsd.org/Python/CompiledPackages

Fixes reports of Python port builds as root failing on filesystem
violations due to bytecode file writes where the port did not include
them in the package.

For those ports/packages that currently package bytecode, some
checksum mismatches on those files may occur. This is harmless and
will be rectified, in large as part of a USE_PYTHON=distutils
overhaul to reduce churn.

While here, implement a long-standing todo item of letting lang/python
ports use python.mk bits. Not only does this obviate duplicate
variables in each Makefile, but SUB_LIST (also added) is used for
these triggers.
