math/py-matplotlib2: Remove expired port

2023-09-30 math/py-matplotlib2: Upstream support ended in 2020 and do not
support python3 versions existing on the tree

math/py-matplotlib2: Mark BROKEN on 14

- Fails to compile with:
  ISO C++17 does not allow 'register' storage class specifier
- Although this specific has easy workarounds but it fails at the stage
  post-stage with the following:
  ====> Compressing man pages (compress-man)
  pkill -15 -F /tmp/.xvfb-0.pid
  pkill: Pidfile `/tmp/.xvfb-0.pid' is empty

  The result remains unchanged even with other llvm variants.
- Mark DEPRECATED as upstream support reached EOL during 2020. See the
  following for more information:
  https://discourse.matplotlib.org/t/ann-matplotlib-2-2-0-released/20227
  Also this does not officially support python3.8 and later.
- Set EXPIRATION_DATE to 2023-09-30

all: remove explicit versions in USES=python for "3.x+"

The logic in USES=python will automatically convert this to 3.8+ by
itself.

Adjust two ports that only had Python 3.7 mentioned but build fine
on Python 3.8 too.

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Approved by:		portmgr (tcberner)

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

math: remove 'Created by' lines

PyQt: Update sip to 6.5.0, reintroduce sip4 and simplify PyQt framework.

SIP:
As mentioned in the update from sip to sip5, this is a transitional version
to remove what is deprecated in sip4.
Sip6 completely removes the deprecated parts.
Unfortunately, some ports — mostly cura things — can not use sip6, so we
reintroduce sip4.

PyQt:
At the same time, we took the opportunity to simplify PyQT and propose only one
package as for devel/pyside2. */py-qt5-* have been merged — excepted chart,
networkauth and webengine — into devel/py-qt5-pyqt.

This allows us to be in adequacy with the packages that the author of these
