textproc/libxml2: really update to 2.15.1

Changelog: https://gitlab.gnome.org/GNOME/libxml2/-/blob/2.15/NEWS

Notably, all documentation generation requires a circular dependency
on textproc/libxslt. While the API documentation, in HTML, lives
on the upstream site [0], the man pages are now pre-rendered manually.

Also includes an upstream commit addressing unsafe pointer usage
in XPath, leading to security bugs in consumers like libxslt
(CVE-2025-10911). [1]

Mark the -python child port DEPRECATED without expiration date since
upstream has not provided a firm one yet, particularly the release
schedule for the next major version 2.16.

Revert "textproc/libxml2*: update to 2.15.1, split -core"

The design of this update was repeatedly rejected in the linked PR
with a prescribed different design. This commit is therefore
unauthorised.

This reverts commit 099bd713e09ebdd02d73fde770c50706f980404f.

textproc/libxml2*: update to 2.15.1, split -core

libxml2 now requires xsltproc from libxslt to build,
yet libxslt depends on libxml2,
so we need to break a dependency cycle.
documentation needed to be split out to a separate port.

libxml2 has therefore been split into two ports,
* libxml2 builds the documentation (unless disabled),
* library and executables in libxml2-core.

Pull in one contributor patch suggested by the former libxml2 maintainer
to address one downstream security issue in recent libxslt versions.

This should address arrowd@'s hint that installing libxml2 should
provide a full-featured package.

While here, deprecate libxml2-python according to upstream plans, we
have very few users in the ports tree, and expire end of 2026Q1.

textproc/libxml2: update to 2.14.4

Changelog: https://gitlab.gnome.org/GNOME/libxml2/-/blob/v2.14.4/NEWS

textproc/py-libxml2 child port is moved to textproc/libxml2-python
to match the Python package name upstream specified; it now USES=python
to build after do-configure. Consumers adjusted to match.

Includes two bug-fix commits.
