*/*: switch dependency from devel/py-lxml5 to devel/py-lxml

Currently, there are two versions of python XML processing library
which conflict each other in the ports tree, namely:
- devel/py-lxml5 (now at version 5.4.0)
- devel/py-lxml  (now at version 6.0.1)

To avoid the situation that some ports depend on py-lxml5 and some
others do on py-lxml (by switching dependencies individually), this
commit switches the dependencies from py-lxml5 to py-lxml at once.

Additional note: There are still two ports (textproc/py-rdflib and
www/py-draftjs-exporter) depending on py-lxml5 since they limit upper
version to less than 6.

*/*: update dependency on devel/py-lxml to devel/py-lxml5 (2nd attempt)

This is a follow up to the commit 230fb2661c78, which updated some
ports' dependencies on devel/py-lxml to devel/py-lxml5. It was an
attempt to follow the dependency change of
www/py-beautifulsoup. However, the switch was incomplete and broke
some other ports.

It has turned out that the ports depending on devel/py-lxml (at
version 4.9.3) does not limit their dependencies' upper bound to 4.x
except for one (devel/py-pymaven-patch). So updating them to
devel/py-lxml5 (at version 5.4.0) should cause no harm.

This commit switch dependencies of all the ports (except
devel/py-pymaven-patch) to devel/py-lxml5 avoid potential conflicts.

python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.
